Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $13 monthly fee
Tpy6a [65]

Answer:

With 250 minutes of calls the cost of the two plans is the same

Step-by-step explanation:

We must write an equation to represent the cost of each call plan.

<u>For the first plan</u>

Monthly fee

 $ 13

Cost per minute

 $ 0.17

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 13 + 0.17x

<u>For the second plan</u>

monthly fee

$ 23

Cost per minute

$ 0.13

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 23 + 0.13x

To know when the cost of both plans are equal, we equate the two equations and solve for x.

13 + 0.17x = 23 + 0.13x\\\\0.17x -0.13x = 23-13\\\\0.04x = 10

x = \frac{10}{0.04}

x = 250\ minutes

With 250 minutes of calls the cost of the two plans is the same: $55.5
