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.

Answer 1

To solve for the total cost \( C \) using the equation \( C = 15 + 3x \), we need to determine the value of \( x \), which represents the number of shoe rentals.

In this case, you want to calculate the cost for four shoe rentals, so \( x = 4 \).

Now, substitute \( x \) into the equation:

\[ C = 15 + 3(4) \]

Calculating the shoe rental cost:

\[ C = 15 + 12 \]

Now, add the values together:

\[ C = 27 \]

Thus, the total cost for getting a lane and four shoe rentals is $27.00.
