The bowling alley charges a flat rate for a lane, plus a fee per shoe rental. Use the equation C = 15 +3x to solve for the cost of getting a lane and four shoe rentals. Enter your answer, including cents.
To solve for the cost of getting a lane and four shoe rentals, we need to plug in x = 4 (since we want four shoe rentals) into the equation C = 15 + 3x.
C = 15 + 3(4)
C = 15 + 12
C = 27
Therefore, the cost of getting a lane and four shoe rentals is $27.
