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.(1 point)
The equation that represents the cost to play based on the number of hours played is:
C = 15 + 5(h-1)
To calculate how much it would cost to play for three hours, we substitute h = 3 into the equation:
C = 15 + 5(3-1)
C = 15 + 5(2)
C = 15 + 10
C = $25.00
