Question

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

a) y = 5x - 2.50 for x ≤ 2; y = 2.50x for x > 2
b) y = 5x + 2.50 for x ≤ 2; y = 2.50x for x > 2
c) y = 5x for x ≤ 2; y = 2.50(x - 2) for x > 2
d) y = 5x - 2.50 for all x

Answer 1

The equation that describes the total cost y as a function of the hours x for the downtown parking lot is y = 5x - 2.50 for x ≤ 2; y = 2.50x for x > 2.

Step-by-step explanation:

The equation that describes the total cost y as a function of the hours x for the downtown parking lot is:

For x ≤ 2: y = 5x - 2.50

For x > 2: y = 2.50x

So, the answer is a) y = 5x - 2.50 for x ≤ 2; y = 2.50x for x > 2.
