Answer 1

The correct interpretation of the function \( y = 15x + 12 \) in the context of the gym fees is:

y is the cost and x is the number of months someone is a member of the gym; $12 is the enrollment fee and $15 is the monthly fee.

In this function:

• \( y \) represents the total cost.
• \( x \) represents the number of months of membership.
• The \( 12 \) is the one-time enrollment fee.
• The \( 15 \) is the monthly fee charged for each month of membership.

Thus, the correct response aligns with this interpretation.
