Answer:

Step-by-step explanation:

For this problem, you have to find out how much each cereal costs per ounce. So you must divide each price by the amount of cereal you get and compare:

$4.08/16oz=$0.255/oz

Find the unit price ($/oz) of the remaining 2 then compare. The lowest value is the best buy!
