Question

A gym membership has an initial fee of $30 and month,y fee of $18. After how many months will the whole amt cost $138?

Answer 1

Answer: 4 Months

Explanation:

Since you start by paying $18 with the initial one time fee, you then can subtract $18 from the $138 which leaves you with $120 dollars left to hit the $120 mark. You can then set up an equation where x represents amount of months, $120/$30 = x. x = 4.
