Question 316885
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $26 one-time activation fee and charges  7 cents a minute. The second plan has no activation fee and charges 12 cents a minute. After how many minutes of long distance calls will the costs of the two plans be equal?
.
Let t = minutes used
.
First plan:
.07t + 26
Second plan:
.12t
.
Set the two equal to each other and solve for t:
.07t + 26 = .12t
26 = .05t
26/.05 = t
520 minutes = t
