Answer
Malika would pay (20 + 5y) dollars if she makes y visits to the gym on plan A.
Step-by-step explanation
If Malika joined Staywell Gym for one month and choses plan B, she would just pay $40 but if she choses plan A, she would pay $20 monthly fee and subsequent $5 for each visit. If she makes y visits in a month,
Malika will pay [20 + (y × 5)] = (20 + 5y) dollars.
