Answer:
You did not ask a specific answer and only gave us a scenario. Therefore I could only set up equations for both plans. I hope they help!
Step-by-step explanation:
First plan: y = 0.13x + 49
Second plan: y = 0.17x + 40
0.13 and 0.17 = The amount of money Brian has to pay per mile in each plan
x = The number of miles that were driven in each plan
49 and 40 = The base cost of each plan
