Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $20 one-time activation fee and charges 13 cents a minute. The second plan has no activation fee and charges 17 cents a minute. After how many minutes of long distance calls will the costs of the two plans be equal?

  • MATH -

    x = number of minutes

    20 + .13x = .17x

    Solve for x.

    I hope this helps.
