Student budgeted a $25 a month for phone service. If the telephone company charges $18 a month for basic service and $.05 a minute for each long distance call, how many minutes can be spent on long distance calls each month?

35

I'm sorry -- but I goofed.

The problem should be 7 / 0.05 = 140.

He can make 140 long distance calls a month.
