the cost of a family membership at the health club is $58 per hour plus a one-time $129 start up fee. If a family paid $651, then how many months is their membership?
The equation would be 651=58x+129. Subtract 129 from both sides of the equation. you get 522=58x. Then divide both sides of the equation by 58 to get x alone and you get 9=x. The membership is 9 months. Hope I helped and if you have any questions, just leave a comment.
