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.

For the first plan

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:

$c = 13 + 0.17x$

For the second plan

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
