You have a giant bag of M&Ms and are wondering how many there are. You notice that there don’t seem to be nearly as many
USPshnik [31]

Answer:

800 M &Ms

Step-by-step explanation:

First, we can operate on the estimate that the proportion of M&Ms of the sample is equal to the proportion of M&Ms in the giant bag.

Therefore,

number of orange M&Ms in sample / sample size = number of orange M&Ms in bag / bag size

3/50 = 48 / bag size

multiply both sides by 50 to remove a denominator

3  = 48 * 50 / bag size

multiply both sides by bag size to remove the other denominator

3 * bag size = 48 * 50

divide both sides by 3 to isolate bag size

bag size = 48 * 50 / 3

bag size  = 800 M &Ms
