Question

A truck can be rented from company a is $120 a day plus $0.20 per mile. company b charges $40 a day plus &0.60 per mile to rent the same truck. find the number of miles in a day at which the rental costs for company a and company b are the same

Answer 1

First need to make an equation for each

x = Miles
y = Total Cost

Comp A: 120 + 0.20x = y
Comp B: 40 + 0.60x = y

cancel out the amounts to make it easier (Subtract 40 from each)

Comp A: 80 + 0.20x = y
Comp B: 0.60x = y

insert a problem for y to solve for x

 80 + 0.20x = 0.60x

Your answer is 200 miles
