Question

John joined a gym for 6 months. He pays 20$ per month plus a membership fee. If his bill is 150$, what was the membership fee?

Answer 1

x is the number of months and y is the membership fee

$cost = 20x + y$

$150 = 20(6) + y$

$150 = 120 + y$

$150 - 120 = 120 - 120 + y$

$30 = y$

The membership fee was $30.

Answer 2

Answer:

Step-by-step explanation:

If he's been at the gym for 6 months, and he is charged $20 each month, then he has paid $120 dollars, not counting his membership fee. His total bill is $150.

150-120= $30

His membership fee was $30.

Hope this helps!
