Question

It costs $100 to join a fitness center plus a monthly fee. You spent $700 last year at the fitness center. How much was the monthly fee? Write and solve an equation to determine the monthly fee

Answer 1

Assume you went there for 12 months last year.

Equation:

100 + 12x = 700

Subtract 100 from both sides.

12x = 600

Divide 12

x = 50
