Question

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)

Answer 1

Answer: In 19 weeks I will have enough money to buy the bike.

Explanation:

Saved Money = $125.

Needed Money = $500-$125= $375

In 1 week $20 so $375/$20 = 18.75 weeks

In 19 weeks it would be $19*20= $380

Answer 2

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).
