Question

A 13-ounce package of pistachios costs $5.99. What's the unit rate?

Answer 1

The unit rate is $0.46 per ounce because $5.99/13oz=$0.46/oz. 

Answer 2

we know that

A rate is a ratio that compares quantities in different units. A unit rate is a rate where the second quantity is one unit

so

In this problem to find the unit rate

Divide $
`5.99` by
`13\ ounces`

`unit\ rate=(5.99)/(13)(dollars)/(ounce) \\ \\ unit\ rate=0.46(dollars)/(ounce)`

therefore

the answer is

the unit rate is equal to
`0.46(dollars)/(ounce)`
