Question

(Full Problem)

Claudia wants to rent a car. She calls two companies. Hot Wheels Auto Rentals charges a flat rate of $90.00 plus $0.18 per mile traveled. Grand Auto charges a flat rate of $75.00 plus $0.15 per mile traveled. For what driving distance would Claudia pay the same amount for both companies? Write an equation to solve the problem.

Answer 1

Set m = to the number of miles traveled.

Now you can create two algebraic expressions to represent what each company charges. For example, Hot Wheels would charge 90+0.18*m. Do the same for Grand Auto, then set the expressions equal to each other. Solve for m.
