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.
[tex]\begin{gathered} \$1=100\text{ cents} \\ \implies\$7.36=7.36\times100=736\text{ cents} \end{gathered}[/tex]Next, to find the unit rate, divide the number of cents by the number of minutes.
[tex]\text{Unit Rate}=\frac{736\text{ cents}}{16\text{ minutes}}=46\frac{\text{ cents}}{\text{minute}}[/tex]The unit rate is 46 cents per minute.
