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
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)
