Jessie Cummings · Answer 1

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.

Werner · Answer 2

At 100 minutes, the plans are equal in cost.

Step-by-step explanation:

1900+13x=2400+8x

5x=500

x=100
