Answer 1

The correct interpretation of the function $y=15x+12$ in the context of the gym's charges is as follows:

• $y$ represents the total cost.
• $x$ represents the number of months someone is a member of the gym.
• The term $15x$ indicates that for each month of membership, there is a charge of $15.
• The term $12$ represents the one-time enrollment fee.

Thus, the correct statement 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.
