To solve for the cost \( C \) of getting a lane and four shoe rentals using the equation \( C = 15 + 3x \), where \( x \) is the number of shoe rentals, we need to substitute \( x \) with the number of shoe rentals.
Given that you want to rent 4 pairs of shoes:
1. Substitute \( x \) with 4 in the equation:
\[
C = 15 + 3(4)
\]
2. Calculate \( 3(4) \):
\[
3(4) = 12
\]
3. Now substitute back into the equation:
\[
C = 15 + 12
\]
4. Add the two amounts:
\[
C = 27
\]
Thus, the total cost for getting a lane and four shoe rentals is \( \boxed{27.00} \).
