Monica wants to buy soup. Store a has a special-5 cans for $10. Store b sells 3 cans for $9. If she wants to buy 16 cans what would be the better deal

Answer 1

5 for 10 is $2 per can and $32 for 16

3 for $9 is $3 per can and $48 for 16

2<3, 32<48

5 for $10 is the better deal for any number of cans, unless all you wanted were 3 cans

volume discounts are usually cheaper, unless you don't need the larger volume
