The monthly cost per minute of cellular phone service is $0.0047.

SOLUTION:

Given, Cellular phone service is available for $8 per month for 1680 minutes.

We need to find what is the monthly cost per minute?

monthly cost per minute is nothing but amount paid in the month divided by the total talking time in minutes.

Here, amount paid in one month = $8

And, total talking time = 1680 minutes.

Now, monthly cost per minute =
`$\frac{\text { amount paid }}{\text { talking time in minutes }}$`

`=(8)/(1680) \\\\=(1)/(210)$`

= 0.004762 approximately

Hence, the monthly cost per minute is $0.0047.
