Question

A volunteer made m muffins for the bake sale. After selling 28 muffins, 21 muffins remained. Write and solve an algebraic equation to find how many muffins she originally made. *

Answer 1

The original amount of muffin she original made will be: m = 49

Explanation:

• Let 'm' be the muffins made for the bake sale.

Given that after selling 28 muffins, 21 muffins remained.

Thus, the equation becomes

`m - 28 = 21`

adding 28 to both sides

`m-28+28 = 21+28`

`m = 49`

Therefore, we conclude that the original amount of muffin she original made will be: m = 49
