Evan pays $12 per month to belong to a gym so that he can swim in the gym’s pool. Each time he swims he pays an additional $2. He uses the function e 5 2t 1 12 to track his monthly swimming expenses, where e represents total expenses and t represents number of times Evan swims. Make an input- output table, graph your results, and determine if the function has a proportional relationship. Explain.
