Question

A formula for estimating the weight of a trout (from measurements) is

W =

LG2

800

where L is its length and G is its girth (the distance around the body of the fish at its largest point), both measured in inches. The weight of the fish W is in pounds. A trout caught by Ashley is 20% longer and has a girth that is 15% shorter than the one caught by Jane.
By how much does the weight of the trout caught by Ashley differ from the weight of the one caught by Jane? (Round your answer to one decimal place.)
