What answer do you get?
To determine the cost per minute of the phone call, divide the total charge by the duration of the call. In this case, you would divide 80 cents by 15 minutes.
To do the calculation, take the following steps:
1. Convert the cents into decimal form: 80 cents = $0.80
2. Divide the total charge ($0.80) by the duration of the call (15 minutes): $0.80 / 15 min = $0.0533 per minute.
Therefore, the cost of the phone call is approximately 5.33 cents per minute.
