Jenny purchased a prepaid phone card for $20. The long distance calls cost 10 cents a minute using this card. Jenny used her card only once to make a long distance phone call. If her remaining credit on the card is $18.90. How many minutes did her call last?
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $24 one-time activation fee and charges 14 cents a minute. The second plan has no activation fee and charges 18 cents a minute. After how many minutes of long distance calls will the costs of the two plans be equal?
