Question

A local arcade charges $15.00 for unlimited play time for the first hour, then $5.00 per additional hour. On a piece of paper, write an equation that represents the cost to play, C, based on the number of hours played, h. Then use the equation to calculate how much it would cost to play for three hours. Enter your answer for C, including cents.

Answer 1

The equation that represents the cost to play, C, based on the number of hours played, h, is:
C = 15.00 + 5.00(h-1)
To calculate how much it would cost to play for three hours:
C = 15.00 + 5.00(3-1)
C = 15.00 + 5.00(2)
C = 15.00 + 10.00
C = $25.00
