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

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

he kicked it up? is this the answer ?
