Question

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 cost \( C \) of getting a lane and four shoe rentals, we can use the given equation:

\[
C = 15 + 3x
\]

where \( 15 \) is the flat rate for the lane, \( 3 \) is the fee per shoe rental, and \( x \) is the number of shoe rentals.

Since we need to find the cost for \( 4 \) shoe rentals, we substitute \( x = 4 \) into the equation:

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

Calculating \( 3(4) \):

\[
3(4) = 12
\]

Now we add this to the flat rate:

\[
C = 15 + 12 = 27
\]

Thus, the total cost of getting a lane and four shoe rentals is

\[
\boxed{27}
\]
