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).

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

Step-by-step explanation:

The complete question is

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

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

The C-intercept or initial value is

substitute

For h=3 hours

substitute in the linear equation

therefore

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