A downtown parking lot charges \$5 per hour for the first 2 hours, then \$2.50 per hour after that. Which equation(s) describes the total cost y as a function of the hours x?

1. Y = 5x + 2.5x

2. Y = 5x + 2.5(x-2)

3. Y = 5x for 2 hours or less, then Y =10 + 2.5(x-2) for over 2 hours

4. Y = 5x up to 2 hours then Y = 5x + 2.5x for over 2 hours
