(a) The Feelgood Gym has a monthly membership fee of $100 and it charges an addi- tional $1 per hour. If I use the gym for x hours in a month, write down an expression
for the total cost in terms of x.
(b) Repeat part (a) for the Fabulous Me Gym, which charges $35 per month and $3.50
per hour.
(c) By plotting both graphs on the same axes, or otherwise, find the number of hours
which gives the same total cost.
