Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answer: $84
Step-by-step explanation:
Price of smoke detector in Store A = $17
Price of smoke detector in Store B = $24
Total detectors bought = 12
Price of 12 detectors in Store A = $17 x 12 = $204
Price of 12 detectors in Store B = $24 x 12 = $ 288
Difference = $ 288 -$ 204 = $84
Hence, he will spend $84 less than if he purchased all the smoke detectors at Store B.

The square shown is divided into five cells. Starting at any cell, how many paths can be drawn that move only to adjacent cells and that include all five cells?
Answer:
150 (not sure)
Step-by-step explanation:
Paths that only touch 5 points unrepeatedly:
I used a tree diagram to list all the workable paths, taking cell A as an example:
ABCDEABCEDABECDABEDCAEBCDAEDCBADCBEADCEBADEBCADECB2*(3x2 - 1) = 10
When you start at A you would have 3 choices, but after that only two, and since DB or BD can't happen and crossing B and D for the second step is the same, I double it.
Paths that touch 5 points and reapeat one of them:
2*(3x2x2 - 1x2) = 20
Paths that touch 5 points and repeat two of them:
2*(3x2x2x2-1x2x2) = 40
Paths that touch 5 points and repeat three of them:
2*(3x2x2x2x2-1x2x2x2) = 80
The sum of the answers in these 4 senarios is the final answer.

On a busy day, a vet thought the practice saw 28 cats. The actual number was 24 cats. What is the percent error between the vet's estimate and the actual amount? Round your answer to the nearest hundredths.
Answer:
16.67%
Step-by-step explanation:
A vet taught the practice saw 28 cats
The actual number was 24 cats
Therefore the percent value can be calculated as follows
= approximate value- exact value/exact value × 100
= 28-24/24 × 100
= 4/24 × 100
= 0.16666 × 100
= 16.666
= 16.67 % ( to the nearest hundredth)

$130 plus a 20% tip is how much money
Answer:
$156
Step-by-step explanation:
130 times 20% = 26, 130 plus 26 = 156
Answer:
156 dollars
Step-by-step explanation:
You just multiply 130 with 1.2, because the 1 represents the whole, or 130, and the 0.2 represents the 20% tip .
130 x 1.2 = 156

Tina borrows $4,000 at a simple interest rate of 2% and plans on paying their loan over 6 years. What is the total amount Tina will have to repay on both the loan and interest? *
Answer:
$4480Step-by-step explanation:
Given
principal= $4000
rate= 2%= 0.02
time= 6 years
We know that the expression for simple interest is given as
Interest = PRT
solving for the interest we have
I=4000*0.02*6
I=480
Therefore Tina is paying an interest of $480
Tina will have to repay on both the loan and interest of
=4000+480
=$4480

Answer:
A) where any seats empty? How do u know?
Yes, there were empty seats.
B) if ur answer to part a is yes find the number of empty seats
440 empty seats
Step-by-step explanation:
A) where any seats empty? How do u know?
Yes there were empty sits
B) if ur answer to part a is yes find the number of empty seats
We are told that the theater had the theartre has 49 rows with 48 seats in each row
This means the total number of seats in the theater =
49 × 48 = 2352 seats
The total number of people in the theater
= Number of teacher + Number of Students
= 1854 + 58 = 1912 people
This means 1912 seats were occupied
The number of empty seats = 2352 - 1912
= 440 seats
