Great calls has a special plan offer this month. there is a $6.00 per month charge each month and calls anywhere in the united states are $0.04 per minute. what would the monthly cost be if you typically talk for 550 minutes per month
Call cost per minute = $0.04
Number of minutes talked = 550
Call charges for 550 minutes @ $0.04 = $22
We should add the monthly charge of $6 to this call charges because that too is a part of our call cost. So the total cost would be $22 + 6 = 28.
