The first hour is free, and the rest charges is $2.50
Let x be the time.
Let y be the total
Your equation will look like
When x < 2, y = 0
When x > 1, y = $2.50(x)
So:
1 < x < ∞ for hours, then equation will look like:
y = total amount
$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.
$2.50x - $2.50 = y should be your equation.
hope this helps
