Answer:

46 cents per minute.

Explanation:

The long-distance call costs $7.36 for 16 minutes.

The goal is to determine the unit rate in cents per minute.

In order to do this, first convert the amount, $7.36 to cents.


\begin{gathered} \$1=100\text{ cents} \\ \implies\$7.36=7.36*100=736\text{ cents} \end{gathered}

Next, to find the unit rate, divide the number of cents by the number of minutes.


\text{Unit Rate}=\frac{736\text{ cents}}{16\text{ minutes}}=46\frac{\text{ cents}}{\text{minute}}

The unit rate is 46 cents per minute.
