PLEASE HELP To rent a carpet cleaner, Tools To Go charges $15.00 for the first hour or part of an hour plus $3.50 for each additional half hour or part of a half hour.

a. Tim picked up a carpet cleaner at 8:10 a. m. and returned it at 4:10 p. m. Determine his rental charge.

b. Calculate the average cost per hour for Tim’s rental.

c. Charmaine rented a carpet cleaner from Carpet Emporium. Her bill was $59.40 for 5.5 h. Compare the average cost per hour for Charmaine’s rental with the average cost per hour for Tim’s rental. How many times as much was Charmaine’s rental?

Step-by-step explanation:

You want to start by creating an equation to find out how much it could cost to rent a carpet cleaner

y= total cost

x=each additional half an hour

y = 3.5(x) + 15

a. Tim rented the carpet cleaner for 4 hours

The first hour is 15

So he had the carpet cleaner for 3 extra hours of 6 addition half an hours

y = 3.5x +15

y = 3.5(6) + 15

y = 21 +15

y= 36

$36

b.

average is mean

add up all the costs and divide by the number of hours

To figure out how much each additional hour is, multiply 3.5 by 2, which means that each additional hour is $7

Add up 15, 7, 7,and 7

15+7+7+7= 15+21= 36

Now divide by 4 to find the average

36/4 = 9

$9 is the average

c.

Start by dividing 59.4 by 5.5

59.4/5.5 = 10.8

$10.8 was the average cost per hour for Charmaine's rental

Now do 10.8/9 to find out how many times as much Charmalaines rental was

10.8/9 = 1.2

Charmaine's rental is 1.2 times Tim's rental

add 5 subtract 1

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
