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:
<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:
To know when the cost of both plans are equal, we equate the two equations and solve for x.
With 250 minutes of calls the cost of the two plans is the same: $55.5
