Question

1. Five Star Carz rents cars for $28 plus $0.05 per mile, and GoCars rents cars for $25 plus

Answer 1

Answer:

A. System:

y = 0.05x + 28

y = 0.07x + 25

B. Substitute:

0.07x + 25 = 0.05x + 28

C. At what number of miles will the cost the same?

150

Step-by-step explanation:

Let y = cost. Let x = number of miles.

Five Star CArz:

y = 0.05x + 28

GoCars:

y = 0.07x + 25

System of equations:

y = 0.05x + 28

y = 0.07x + 25

Substitute y of the first equation with 0.07x + 25

0.07x + 25 = 0.05x + 28

0.02x = 3

x = 150

The costs are the same at 150 miles.
