Question 1096532
let m = no. of miles
A truck can be rented from Company A for ​$70 a day plus ​$0.60 per mile.
A Cost = .6m + 70
 Company B charges ​$50 a day plus ​$0.70 per mile to rent the same truck.
B cost = .7m + 50
 Find the number of miles in a day at which the rental costs for Company A and Company B are the same. 
.7m + 50 = .6m + 70
.7m - .6m = 70 - 50
.1m = 20
m = 20/.1
m = 200 miles they cost the same

Check this find the actual cost of each
.6(200) + 70 = $190
.7(200) + 50 = $190
