8. 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.

Answer 1

To find the total cost \( C \) for getting a lane and four shoe rentals using the equation \( C = 15 + 3x \), you'll need to substitute \( x \) (the number of shoe rentals) with 4.

1. Substitute \( x = 4 \) into the equation: \[ C = 15 + 3(4) \]

2. Calculate \( 3(4) \): \[ 3(4) = 12 \]

3. Now add that to 15: \[ C = 15 + 12 \] \[ C = 27 \]

So, the total cost of getting a lane and four shoe rentals is $27.
