Question

Mr. Wagner is on a diet. He currently weighs 250 pounds. He loses 3 pounds per month. Write an equation that represents his weight after m months. After how many months will Mr. Wagner reach his goal of 220 pounds.

Answer 1

10 months

Explanation:

220+3m = 250

Subtract 220 from both sides, now it is 3m=30. So now divide 3 on both sides. So now we have our answer m=10.

Answer 2

y=mx+b

Explanation:

In this case, x is represented by m. B is how much he weighs at the start which is 250. How many pounds does he lose per month ? 3. Thus, we conclude:

220=3x+250
