$4.08/16 ounces: $0.255

$4.50/18 ounces: $0.25

$5.39/22 ounces: $0.245


The best buy would be $4.50 for an 18-ounce box of cereal.

apologiabiology
you want to find the cheapest per 1 ounce

so just divide cost by ounces

4.08/16=0.225 per ounce
4.50/18=0.250 per ounce
5.39/22=0.245 per ounce
4<5
so cheapest is the 22oz box be
