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

$0.13

for each minute of calls. The second plan has a

$28

monthly fee and charges an additional

$0.09

for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

Answer provided by our tutors

Let

x = the number of minutes for which the costs of the two plans will be equal

24 + 0.13x = 28 + 0.09x

........

by solving we find

x = 100 min

For 100 minutes the cost of the two plans will be equal.
