Step 1:
Let us first find the decrease in amount.
Decrease in amount = 150 -120 = $30
Step 2:
Now let us find the ratio of decrease in price to original price.
So the ratio is 1/5 or in decimal its 0.2.
Step 3:
To find percentage decrease we change this decimal number 0.2 two places to the right side, so it becomes 20 %
The price decreased by 20%

While reviewing last months finances Oscar noticed that he had spent $200 on a wedding cake and deposited $500 and he just earned from selling books to a used bookstore down here again spent $127 to buy some new box which integer represents the change an Oscar savings
Answer:
an additional $173.
Step-by-step explanation:
The change in Oscar's savings is calculated by adding or subtracting all of the different transactions that have occurred. First, he spent $200 which would be a deduction and be subtracted from his initial balance. Next, he deposited $500 which is added to his balance, and lastly, he spent $127 which is subtracted from his balance. Like so...
-200 + 500 - 127 = $173
The final result is positive $173, this means that the change from his initial balance to his current savings balance is an additional $173.
A boat can travel 32 miles on 4 gallons of gasoline. How much gasoline will it need to go 48 miles?
Answer:
6 gallons
Step-by-step explanation:
32/4=8
48/8=6
Answer: 6
Step-by-step explanation: If 4 gallons can take you 32 miles, divide 4 into 32 to get 8. That means 8 miles is 1 gallon. Now just do 48/8 to get 6.
[tex]\sqrt8a-5-\sqrt6a+8=0[/tex]
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
You would start by writing it out again then simplifying.
[tex]\sqrt{8}a-5-\sqrt{6}a+8=0\\.378937a+3=0[/tex]
Now let's subtract 3 from both sides...
[tex].378937a=-3[/tex]
Now we'll divide the sides by .378937....
[tex]a=-7.916883[/tex]
So a equals -7.916883
VGeorge has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money. Look at the numerical expression George used: 15 − 9 + 2.65 + 1.35 + 2(1.74) Can you help him determine why he does not have enough money?
Given:
George has $15.
He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money.
George used: 15 − 9 + 2.65 + 1.35 + 2(1.74)
To find:
Why he does not have enough money.
Solution:
Money her has = $15
All the expenses movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) must be subtracted from the money he has instead of adding these values.
George add the cost of pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each), therefore, he does not have enough money.
Remaining Amount = [tex]15-9-2.65-1.35-2(1.74)[/tex]
[tex]=15-9-2.65-1.35-3.48[/tex]
[tex]=15-16.48[/tex]
[tex]=-1.48[/tex]
Remaining money cannot be negative. Here expenses are more than the money he has. Therefore, he does not have enough money.
Answer:
it's not the best answer but i hope it helps
Step-by-step explanation:
George only has $15 dollars left. He spend $9.00 on a movie ticket and $2.65 on a pretzel. $9.00 - $2.65 would leave him with $6.35. Then, George decided to buy a drink for $1.35. George then wanted to get two veggie cups both for the price of $1.74, but if you subtract $1.35 - $1.74 thus would leave him with $0.39 and he wouldn't have enough money to buy both veggie cups. If George had $1.38 left then he would have enough to buy both veggie cups.

-17(y-2) = -17y + 64
Answer:
No solution.
Step-by-step explanation:
Step 1: Write equation
-17(y - 2) = -17y + 64
Step 2: Solve for y
Distribute -17: -17y + 34 = -17y + 64Add 17y on both sides: 34 ≠ 64Here we see that we get y = no solution. You could also think about it as 2 parallel lines; they have the same slope but different y-intercepts so therefore there will be no intersection/no solution.

The table shows the price for different numbers of chocolate boxes:
Number of Chocolate Boxes Price (in dollars)
2 10
3 15
4 20
5 25
Does this table of numbers represent a proportional relationship? (1 point)
No, because the price of 3 boxes should be $11
No, because the price of 4 boxes should be $40
Yes, because 5 times the price is the number of boxes
Yes, because the price is 5 times the number of boxes
Twenty-seven minus of a number (x) is not more than 36. What is the number?
A.
x > 42
B.
x ≥ -6
C.
x < 3
D.
x ≤ -6
Answer:
Step-by-step explanation:
Symbolically, we have: 27 - x ≤ 36.
We want to solve for x. To do this add x to both sides, obtaining:
27 ≤ x + 36.
Isolate x by subtracting 36 from both sides: -9 ≤ x or x ≥ -9

Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8
Answer:
y = -4/3x + 3
Step-by-step explanation:
3x − 4y = −8
-4y = -3x - 8
y = 3/4x + 2
slope m = 3/4
perpendicular version of it is opposite inverse: -4/3
y-intercept through point (0, 3):
y = mx + b
3 = -4/3(0) + b
b = 3
Use the perpendicular slope with b from above to form new perpendicular equation of line:
y = mx + b
y = -4/3x + 3
What's the equation of a line that passes through (3, 4) and (0, -2)

Caleb is making a soil mix that is 3 parts peat moss to 12 parts dirt. How much dirt should he use for every 1 cup of peat moss?
A He should add cup of dirt
B. He should add cup of dirt.
4
He should add 3 cups of dirt.
He should add 4 cups of dirt
Answer:
He should use 4 cups of dirt, Choice D
Step-by-step explanation:
Ratio of moss to dirt: 3:12 The ratio simplifies to 1:4
This shows that for every cup of moss, he should use 4 cups of dirt as the ratio says.
Answer:
4 cups of dirt
Step-by-step explanation:
since it is a ratio of 3:12, it can be put as a fraction of 3/12 which can be simplified to 1/4 thus is the ratio of 1:4 thus 1 part peat moss to 4 parts dirt and since the measurement is cup, you change parts to cups and you have your answer.

Jack works after school. Each day he is paid a set amount, plus an hourly wage.
Hours 1 1.5 2 2.5 3
Pay 18 23 28 33 38
Which is a reasonable domain for the function f(x) = 10x + 8?
A. 0 < x < 6
B. 0 < x < 24
C. 0 < x < 68
D. 0 < x < 248
Answer:
The correct option is;
A. 0 < x < 6
Step-by-step explanation:
The given data indicates how much Jack is paid on hourly wage is presented here as follows;
Hours [tex]{}[/tex] Pay
1 [tex]{}[/tex] 18
1.5 [tex]{}[/tex] 23
2 [tex]{}[/tex] 28
2.5 [tex]{}[/tex] 33
3 [tex]{}[/tex] 38
Given that the domain is the number of hours worked by Jack after school, and that he receives a set amount at all values of the number of hours worked, a reasonable domain is from 0, at which the pay is 8, to 6 which is less than the normal 8 hours a day job, as he works part time.
Therefore, the correct option is;
A. 0 < x < 6.

Sodium inc borrowed 280000in April 1the note requires interest at 12% and principal to be paid in one year, how much interest is recognized for the period from April 1 to December 31?
Given:
Principal = 280,000
Rate of interest = 12% per annum.
Time period is from April 1 to December 31.
To find:
The interest recognized for the period from April 1 to December 31.
Solution:
Time period from April 1 to December 31 is 9 months.
12 months = 1 year
1 month = [tex]\dfrac{1}{12}[/tex] year
9 month = [tex]9\times \dfrac{1}{12}[/tex] year
So,
[tex]Time=9\times \dfrac{1}{12}[/tex]
[tex]Time=\dfrac{9}{12}[/tex]
[tex]Time=0.75[/tex]
Formula for interest is
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time.
[tex]I=280,000\times \dfrac{12}{100}\times 0.75[/tex]
[tex]I=25200[/tex]
Therefore, the the interest is 25,200.
