Answer 1

Hi, Issa,

Unit price means should convert the price per bottle into something that is a more uniform size - ounces, in this case. Simply divide the price by the ounces to get the cost per ounce. Surprisingly, the smaller bottle is the better value, at $0.29 per ounce. This is unusual, so please check the numbers.

Answer 2

Unit Price is Price of a Shampoo per ounce. It is a simple division problem and can be done using a basic calculator or pen/paper.

The first size costs $3.98 for 14.2 ounces

Unit Price for this shampoo will be ($3.98/14.2 oz ) = $0.28/oz ( rounded off to nearest cent)

The second size costs $9.98 for 33.9 ounces

Unit Price for the second shampoo will be ($9.98/33.9 oz) = $0.29/oz(also rounded off to nearest cent)

There is just 0.01 cent difference between the two. While both could be rounded off to $0.3/oz, the first size is better buy for Unit Price
