Answer 2

Answer:

There were 140 M&M's in the bag to start.

Step-by-step explanation:

Note: The word "of" is a good indicator of multiplication in word problems.

Let's say x is the number of M&M's in the bag. Then,

21=x*15%

Solve for x by dividing by 15% on both sides

140=x

There were 140 M&M's in the bag to start.
