Question

find the unit price(dollars per ounce)Dont understand please help me:
A 20 ounce can of pineapple juice for $0.98

Answer 1

It is $0.98 per 20 oz.
\[\frac{ 0.98~dollar }{ 20~~oz }\]
The units are already correct dollars per ounce, you just have to simplify the numbers by dividing to get dollars per 1 ounce

\[\frac{ 0.049~~dollars }{ 1~~oz }\]

Round that to 0.05 dollars, or 5 cents
