How much does a customer at David's
alina1380 [7]

Answer:

The solution as an ordered pair is (3,21)

Step-by-step explanation:

<u><em>The complete question is</em></u>

At David's skateboard shop, customers pay an  upfront fee of $12 and then pay $3 per  hour for each hour they use the skateboard.

How much does a customer at David's  skateboard shop pay to rent a skateboard  for 3 hours?

Write your answer as an  ordered pair (h,C)

we know that

The linear equation in slope intercept form is equal to

C=mh+b

where

C is the total cost to rent a skateboard

h is the number of hours

m is the slope or unit rate

b is the initial value (the C-intercept)

In this problem we have

The slope is equal to

m=\$3\ per\ hour

The C-intercept or initial value is

b=\$12

substitute

C=3h+12

For h=3 hours

substitute in the linear equation

C=3(3)+12=\$21

therefore

The solution as an ordered pair is (3,21)
