Answer:
The original amount of muffin she original made will be: m = 49
Step-by-step explanation:
- Let 'm' be the muffins made for the bake sale.
Given that after selling 28 muffins, 21 muffins remained.
Thus, the equation becomes
[tex]m - 28 = 21[/tex]
adding 28 to both sides
[tex]m-28+28 = 21+28[/tex]
[tex]m = 49[/tex]
Therefore, we conclude that the original amount of muffin she original made will be: m = 49
