How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

For this case, we're provided that:

For product A:

• 8 oz. bottle of cough medication is of $1.36

For product B:

• 16 oz. bottle of cough medication is of $3.20

Calculating unit price:

• For product A:

8 oz of cough medication costs 1.36 dollars

1 oz will cost 1.36/8 = 0.17 dollars (divided price and amount both by 8)

Thus, the price of unit cough medication  of product A = 0.17 dollars.

• For product B:

16 oz of cough medication costs 3.20 dollars

1 oz will cost 3.20/16 = 0.20 dollars (divided price and amount both by 16)

Thus, the price of unit cough medication  of product B = 0.20 dollars.

So we see, as 0.17 < 0.20, thus, the product that has lower unit price for the cough medication in this case is product A
