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