Question

you can buy 3 apples at the quick market for $1.08. You can buy 5 of the same apples at stop and save for $2.40. which place is the better buy?

Answer 1

at the quick market each apple is 36 cents and at the other shop its 48 cents 
so the first shop has the better deal by 12 cents

Answer 2

$\frac{1.08}{3}= 0.36$ 
So one apple at Quick Market is $0.36
$\frac{2.40}{5} =0.48$
So one apple at Stop and Save is $0.48. 

Since one apple at Quick Market is cheaper, your answer would be Quick Market. 

I hope this helps! =)
