Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $24 monthly fee and charges an additional $.13 for each minute of calls. The second plan has no monthly fee but charges $.17 for each minute of calls. For how many minutes of calls will the cost of the two phone plans be equal

Respuesta :

Answer:

600 minutes

Step-by-step explanation:

Let's make the two equations equal to each other.

24 + .13x = .17x

Subtract .13x from both sides.

24 = .17x - .13x

24 = .04x

Divide by .04 on both sides to get the value of x.

24/.04 = 600

x = 600

Therefore, for 600 minutes of calls will the cost of the two phone plans be equal.
