The average weight of 5 items is 24 pounds. If the total weight of 3 blue items is 39 pounds, what is the average weight of the remaining 2 non-blue items?

Answer: the average weight of the remaining 2 non-blue items is 81 pounds

Step-by-step explanation:

The formula for determining average is expressed as

Average = sum of each item / total number of items

Let x represent the average weight of the remaining 2 non-blue items.

The average weight of 5 items is 24 pounds. If the total weight of 3 blue items is 39 pounds, it means that

(x + 39) / 5 = 24

x + 39 = 5 * 24 = 120

x = 120 - 39

x = 81
