In January, Clarisa signed up for a membership at First Avenue Gym. The plan she chose cost $95 in start-up fees and then $20 per month starting in February. Manny also signed up at First Avenue Gym in January. His plan cost $35 per month starting in February, and his start-up fees were waived.
Create tables for both Clarisa and Manny that compare the number of months since January to the total cost of their
gym memberships. Continue this table for one year. Plot the points from the two tables above on the coordinate plane. Decide if either or both gym memberships are described by a proportional relationship.
