a cellular phone company offers a package

Question

the charge is $39.99 per month, and it includes up to 400 min of statewide calling time. Minutes over 400 are charged at a rate of $0.20 per minute. Determine the total charge for using a cell phone for 483 in one month 

Answer 1

Total = monthly charge + minutes over

 

Monthly Charge = $39.99

 

483 Minutes used - 400 included minutes = 83 minutes over

 

Overage = (83 minutes x $0.20 per minute) = $16.60 

 

Total = 39.99 + 16.60 = $56.59
