Company A charges $80 and allows unlimited mileage. Company B has an initial fee of $65 and charges $0.60 for every mile driven.

Question

Use m for mileage and solve for m.

Answer 1

First, what does it mean to "solve for m"?

 

If it means how many miles would it be if company B charges the same as company A...

 

A = 80

B = 65 + .60 * m         (where * means multiply)

 

Set A = B

 

80 = 65 + .60 * m

15 = .60 * m

 

Can you finish solving this equation for m?

Hint: It might help to use 6/10 in place of .60

since sixty cents is 60/100 or 6/10 of a dollar
