11 You are renting a car for a trip. You call two different rental car places about prices. Each rental place charges a set-up fee for renting a car per day and a price per miles driven.

Find the number of miles when both companies will be the same cost.

Step-by-step explanation:

m is number of miles

A: 45+0.21m (45 is the initial cost)

B: 28+0.38m (28 is the initial cost)

To know how in many miles the cost will be equal,

45+0.21m=28+0.38m

0.38m-0.21m=45-28

0.17m=17

m=17/0.17 = 100

So, at 100 miles the cost will be same for company A and B.
