Question

n a 12 ounce bag of trail mix you notice that there are 18 M&Ms. You now purchase a 20 ounce bag of trail mix. How many M&Ms would you expect to find?

Answer 1

30 M&Ms

1) Gathering the data

12-ounce bag of trail mix = 18 M&Ms

20-ounce bag=?

2) Assuming that the M&Ms are placed in following a constant rate we can write the following proportion:

12 --------------- 18

20 --------------- y

Cross multiplying it due to the first property of proportions

12y =20 x 18

12y = 360

y=30

3) So, I'd expect to find 30 M&Ms at a 20-ounce bag of trail mix.
