Question

a gym membership costs $20 per month and a one - time sign - up fee of $30. what equation represents the total cost t after m months?
a. t = 30m + 20
b. t = 50m
c. t = 20m + 30
d. t = 20 - 30m
a consulting firm has an initial fee of $300 and charges $150 per meeting. model the total fee f for m meetings.
a. f = 450m
b. f = 150 + 300m
c. f = 300 + 150m
d. f = 300 - 150m

Explanation:

Step1: Gym membership cost

Total cost = monthly cost×months + sign-up fee → \( T = 20m + 30 \)

Step2: Consulting firm fee

Total fee = initial fee + per-meeting cost×meetings → \( F = 300 + 150m \)

Answer:

C. \( T = 20m + 30 \)
C. \( F = 300 + 150m \)
