Answer:
175 Miles has to be driven to do the plans cost the same.
Explanation:
Assume The Chau Drive Y miles .
We Have Given Two Plans ,
- First Plan = 50$ + 0.19$ × Y
- Second Plan = 57$ + 0.15$ × Y
Now,Put First Plan=Second Plan (When Both Plans Cost The Same)
50$ + 0.19$ × Y = 57$ + 0.15$ × Y
0.04$ × Y = 7 ⇔ Y = 175 Miles
