To express the total cost \( y \) as a function of the length of the rental in hours \( x \), we need to account for both the admission fee and the cost of renting skates.
The total cost \( y \) can be calculated as follows:
1. The admission cost is a fixed $8.
2. The cost of renting skates is $4 per hour, so for \( x \) hours, it would be \( 4x \).
Putting this together, the equation that represents the total cost \( y \) in terms of the rental time \( x \) is:
\[
y = 8 + 4x
\]
