Question

There are 5 red cherries and 10 yellow cherries on a plate. If the average weight of red cherries is 2 oz and the average weight of the yellow cherries is 3 1/2 oz, what is the average weigh of all cherries on the plate?

Answer 1

45oz

Explanation:

5x2=10

10x3.5=35

35+10=45oz

Answer 2

3 oz.

Explanation:

Average weight = total weight / number of cherries

Weight of red cherries = 5*2 = 10 oz.

Weight of yellow ones = 10* 3 1/2 = 35oz.

So the answer is (10 + 35) / 15 = 45/15

= 3 oz.
