NEED HELP! CAN SOMEONE EXPLAIN HOW OR WHAT IM SUPPOSE TO DO? I NEED A GOOD EXPLAINATION PLEASE

Question

Answer 1

cost per ounce is found by dividing the cost by the number of ounces

1.28/8 = 16 cents per ounce

2.12/32 = about 7 cents per ounce

4.53/36 = about 12 1/2 cents per ounce

6.78/128 = a little over 5 cent per ounce

the gallon (128 ounce) purchase is the best deal, assuming you plan on drinking it all before he goes bad or spoils. It's only about 5 cents per ounce.

the quart purchase though is close, just 7 cents and if it would keep the orange juice fresher, if it's not inconvenient to buy more later. But if it's inconvenient, then the "best" deal is the gallon size.

Answer 2

For each of the four columns divide the price by the ounces. For example, the first column would be

$1.28/8 ounces = $.16/ounce.
