Question

A store owner sells soda in cases of cans and in bottles.

One case of soda contains 24 cans and costs $8.64.
Each can in the case contains 12 ounces of soda.
One bottle of soda costs $1.60 and contains 32 ounces.
What is the difference in cost between 1 ounce of soda in a bottle and 1 ounce of soda in a can?

Answer 1

Explanation:

so for the cans 24*12=288

288/8.64 = cost per ounce for canned

288/8.64=33.3333333 or 33 and 1/3 cents (1/3 of a dollar)

for the bottles we know 32 ounces cost 1.60

31/1.60 = cost per ounce for bottle

31/1.6=19.375 cents (3/8 of a dollar)

8/24 of a dollar for cans and 9/24 of a dollar for bottled

the difference is 1/24 of a dollar, aka 4.16 cents
