asked 02/17/21Customers of a phone company can choose between two service plans for long-distance calls. The first plan has a $15 dollar monthly fee and charges an additional $0.08 for each minute of calls. The second plan has an $8 monthly fee and charges an additional $0.12 for each minute of calls. For how many minutes of calls will the costs of both plans be equal?
