Question

I have a box of M&M bags. Each bag contains 25 M&Ms and are 20% red, 20% brown, 16% yellow, 16% blue, 16% orange, and 12% green.

Jenna needs to collect green M&Ms for a special project. if she needs 100 green M&Ms, how many bags will she need to open?

Answer 1

Each bag contains .12*25 green candies=3

34*3=102, i.e. she will need to open 34 bags (note 33 bags will make only 99 candies).
