Question

A truck can be rented from Company A for ​$60 a day plus ​$.40 per mile. Company B charges ​$40 a day plus ​$.90 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 set up an equation for each company. Company A charges $60 a day and $.40 a mile so you can write that equation as follows:

60 + .40x

Company B charges $40 a day and $.90 a mile so you can write an equation as follows:

40 + 90x

Next set the two equations equal to each other and solve for x:

60 + .40x = 40 + .90x

-.40x -.40x

60 = 40 + .50x

-40 -40

20 = .5x

.5 .5

x = 40

So the number of miles in a day in which the rental costs for Company A and B are the same is 40 miles.

Answer 2

m represents the number of miles

60 + 0.40m = 40 + 0,90m

Can you solve for m and answer?
