3. Which equation below would help you to solve this problem: A new 12
month membership at Workout Nation costs $630. A registration fee of
$150 is paid up front, and the rest is paid monthly. How much do new
members pay each month?
150x + 12 = 630
150x + 12x = 630
150 + 12x = 630
630x + 12 = 150
The x represents the amount of months and it is multiplied by 12 because each month costs 12$. 150 have to be paid up front and this added to the monthly fee is equal to 630$
