Question

A gym charges $40 per month after an initial service fee. One member paid a total of $255 after 6 months. Find the equation that gives the total cost y of a gym membership for x months.

Answer 1

y = 40x +15 because it charges 15$ as it's initial service fee and it charges an additional $40 a month so you multiply 40 times the number of months and add 15 to get the total after x amount of months
