What number of miles results in the same cost for one day?



A. 50 miles

B. 90 miles

C. 100 miles

D. 120 miles

Answer 1

d 120

Explanation:

0.25x + 35 = 0.40x + 17

0.25x -0.40x = 17 - 35

-0.15x = -18

x = -18 / -0.15

x = 120

Answer 2

Lets x is the number of miles

Car Stars Auto Rental charges $35 a day plus $0.25 per mile = 0.25x + 35
Car Express Auto Rental charges $17 a day plus $0.40 per mile =0.40x + 17


0.25x + 35 = 0.40x + 17
0.25x -0.40x = 17 - 35
-0.15x = -18
x = -18 / -0.15
x = 120

answer: D. 120 miles
