Question

A parking garage charges a flat rate for the first hour plus $1.25 for each additional hour of parking. It costs $8.00 to park in the garage for 5 hour. What is the linear equation models the total cost, y, of parking in the garage for x hours?
Please show your work if you can.
A. Y= 1.25x
B. Y= 1.25x + 5
C. Y= 1.25x + 1.75
D. Y= 1.25x + 3

Answer 1

Find the flat rate:

1.25 x 4 = 5.00

8.00 -5.00 = 3

The flat rate is $3

The equation would be:

D. Y= 1.25x + 3
