You have saved $125 to put toward a new bike that cost $500. if you save $20 per week, how long will it take you to save enough to cover the cost? (inequalities)

Well if you use the equation $500=$125+20x, where x=the number of weeks it took to cover the cost, you have to subtract $125 from both sides and you then get 375=20x. Then divide each side by 20, and you get 18.75=x and then round the answer to 19.

So your answer would be 18.75 or 19 weeks (depending on which answer the problem is looking for).
