Question

A family wants to rent a car to go on vacation. Company A charges $50.50 and 9c per mile.

Company B charges $60.50 and 14¢ per mile. How much more does Company B charge for x miles
than Company A

Answer 1

Answer: 0.05x+10

Work Shown:

x = number of miles

Cost of company A = 0.09x+50.50

Cost of company B = 0.14x+60.50

Subtract the two expressions (B-A) to find the difference in price

B-A = (0.14x+60.50)-(0.09x+50.50)

B-A = 0.14x+60.50-0.09x-50.50

B-A = (0.14x-0.09x) + (60.50-50.50)

B-A = 0.05x+10
