Three years ago, Ashly bought $920 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 11 12 % per year. How much is the stock worth now?
Answer:
$1022.304Step-by-step explanation:
Given data
time if investment= 3 years
amount=$920
rate= 11.12%
we want to find the 11.12% of $920 is
= (11.12/100)*920
=0.1112*920
=102.304
Therefore we are going to add the 102.304 to the amount invested which is
102.304+920
=$1022.304
stock worth is $1022.304

The length of a field in yards is a function f(n) of the length n in feet. Write a function rule for this situation. (1 yard = 3 feet)
Appreciate all the support.
(Explanation would be thankful A LOT )
Answer:
[tex]f(n) = 3n[/tex]
Step-by-step explanation:
Given
f(n) --- yards
n --- feet
Required
Write the function rule
From conversion from yard to feet...
We have:
[tex]1\ yard = 3\ feet[/tex]
Multiply both sides by n
[tex]n * 1\ yard = 3\ feet * n[/tex]
[tex]n\ yard = 3n\ feet[/tex]
Replace n yard with f(n)
[tex]f(n) = 3n[/tex]
What is 1,0086 times 1200 divided by 6
By the BODMAS rule the result of 1,0086 times 1200 divided by 6 is 2017200.
10086 times 1200 divided by 6
We can express it mathematically as:
10086 x 1200 ÷ 6
To solve this expression, we will us BOD MAS rule:
Which gives an order in which a mathematical operations should solve.
This order is as:
Brackets, Order, Division,Multiplication, Addition, Subtraction.In the given expression, 10086 x 1200 ÷ 6 there are two mathematical operation division and multiplication.
So according to the BOD MAS order. Division come first and then multiplication.
We will proceed in this order.
Let's solve division:1200÷6
It will result in 200.
Then come to the multiplication operation:10086 x 1200 ÷ 6
Put the value of 1200÷6 in the above expression.
10086 x 1200 ÷ 6 = 10086 x 200
10086 x 1200 ÷ 6 = 2017200.
Hence, following the BODMAS rule, 1,0086 times 1200 divided by 6 will result in 2017200.

Carson runs a farm stand that sells strawberries and bananas. Each pound of
strawberries sells for $3 and each pound of bananas sells for $1.50. Carson sold 4
times as many pounds of strawberries as pounds of bananas and he made $135
altogether. Graphically solve a system of equations in order to determine the number
of pounds of strawberries sold, 2, and the number of pounds of bananas sold, y.
9514 1404 393
Answer:
40 lb strawberries10 lb bananasStep-by-step explanation:
See below for the graph of the equations ...
3x +1.50y = 135 . . . . total from sales
x = 4y . . . . . . . . . . . . strawberry pounds are 4 times banana pounds
The solution is ...
(x, y) = (40, 10)
40 pounds of strawberries and 10 pounds of bananas were sold
Answer: There were 40 pounds of strawberries sold and 10 pounds of bananas sold.
Step-by-step explanation:
x=the number of pounds of strawberries sold
y=the number of pounds of bananas sold

A person places $290 in an investment account earning an annual rate of 2.2%, compounded continuously. Using the formula V = P e r t V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 18 years.
Answer: $430.90
Step-by-step explanation:
Given formula : [tex]V = P e^{ r t}[/tex], where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.
Given: P= $290 , r=2.2% = 0.022 [divide percent by 100 to remove percent sign '%']
Also, t=18 years
Now, [tex]V=290e^{0.022\times18}=290e^{0.396}[/tex]
[tex]=290\times1.48586931755\approx\$430.90[/tex]
Hence, the amount of money in the account after 18 years. = $430.90

Casey went to the store and purchase case 12 pairs of socks.And 3 pairs of shoes for 18.20 each. She spent a total of 81.60. How much did she pay for each sock
Answer:
Casey paid 2.25 in the required currency for each pair of socks.
Step-by-step explanation:
Casey spent a total of $81.60 on both 12 pairs of socks and 3 pairs of shoes.
A pair of shoe = 18.20, then;
3 pairs of shoe = 3 x 18.20
= 54.60
The amount spent on socks = total amount - amount spent on shoes
= 81.60 - 54.60
= 27.00
So that,
The price of each pair of socks = [tex]\frac{amount spent on socks}{number of pairs}[/tex]
= [tex]\frac{27}{12}[/tex]
= 2.25
Casey paid 2.25 in the required currency for each pair of socks.

Nancy Gerald, production control manager at
The Open-Pit Furnace Co., has a total of $497.25 deducted
from her monthly paycheck for Social Security and Medicare
taxes. What is her monthly salary?
Solution
Step-by step
Answer: $6500
Step-by-step explanation:
An employee pays 6.2% as social security and 1.45% as Medicare and the company pays the remaining 7.65%.
Therefore, a total of (6.2% + 1.45%) = 7.65% is deducted from the person income.
Let the monthly salary of Nancy be a
7.65% × a = $497.25
0.0765a = $497.25
a = $497.25/0.0765
a = $6500
Her monthly salary is $6500
The cost of a taxi ride can be modeled as a function of the number miles traveled. There is a base charge of $3.50 and also a charge of $0.10 per mile. A- Write an equation to describe this scenario B- What does the independent variable represent? C- What does the dependent variable represent? D- What is the rate of change in this scenario?
Answer:
a. C(x) = $3.50 + $0.10x. b. distance traveled c. cost of the taxi ride d. $0.10 per mile
Step-by-step explanation:
A. Let C be the cost of the taxi ride and x be the distance traveled in miles. Since there is a base charge of $3.50 and a charge of $0.10 per mile, the cost of the ride is thus
C(x) = $3.50 + $0.10x.
B. The independent variable represents the distance traveled in miles since it is the parameter being measured.
C. The dependent variable represents the cost of the taxi ride, since it is value depends on the parameter (the distance) being measured.
D. The rate of change in this scenario is the $0.10 per mile
