Review for midterm

Question

for a gym membership (m) Suzy paid $12 a month she also paid $2 for each group exercise class (c) during the month write an equation to model the amount of her membership for one month and solve the equation for c

Answer 1

m = 12 + 2c

(m-12) = 2c

(m-12)/2 = c

So for m=$100, she gets (100-12)/2 = 88/2 = 44 classes
