Question

Perfume can be purchased in a 0.6-ounce bottle for $18 or in a 2-ounce bottle for $50. The difference in price per ounce is? HELP PLS!

Answer 1

the answer is $25 because if 2 ounces is $50 then you divide by 2. then you take $25 divided by 5 because there are 5 25s in 100 (0.6 is the same as 0.60)
