Express Car Rentals charges $5 per day to rent a compact car plus a mileage rate of $0.34 per mile. what is the linear equation that relates the cost C to the miles driven M for one day.

Suppose Nadia needs to rent a car from Express for a business trip. Nadia
only carries $98 of cash and she has no credit cards. Set up and solve a linear
equation to find the number of miles that Nadia can drive so that the cost is $98
and she stays within her budget.

Solve the linear equation 9x + 5(2x + 11) = 3(x+21) + 2(8x – 4)

Solve: A(x + y) = C for the variable y.
