Answer :
Say you have hundred dollars ($100) to spend on fruits$40.60
Given data
5 pounds of grapes cost = $3.50
8 pounds of cherries cost = 4.75
Let us estimate how much 100 pounds of grapes will cost
5 pound = 3.5
100 = x
cross multiply
x = 100*3.5/8
x = 350/5
x = $70
Let us estimate how much 100 pounds of cherries will cost
8 pound = 4.75
100 = x
cross multiply
x = 100*4.75/8
x = 475/8
x = $59.375
A better deal is the deal with the lowest cost per hundred pounds
Hence 100 pounds of cherries is the better
you will save
= 100-59.375
= $40.625
to the nearest penny
= $40.60
