Question

5 pencils for 16 dollarsExpress each phrase as a rate and a unit rate (round to the nearest hundredth)

Answer 1

The rate is found by dividing the cost by the number of pencils:

`rate=\frac{16\text{ dollars}}{5\text{ pencils}}`

The unit rate can be found by dividing the numbers to get the amount in dollars a pencil or each pencil cost:

`\text{unit rate}=(16)/(5)\text{dollars per pencil}\approx3.20\text{ dollars per pencil}`
