Unit price is defined as the cost of one unit of an item. Suppose a 16-ounce bottle of shampoo costs $$3.68$. One way to find the unit price (that is, the price of one ounce of shampoo) is to write a proportion such as the one shown below.

$\frac { \$ 3.68 } { 16 oz } = \frac { \$ x } { 1 oz }$

Solving the proportion gives $x = $0.23$, so this shampoo costs $$0.23$ per ounce.
