Respuesta :

85 - 60 = $25 from fees
25 / .10 = 250 minutes
He used 250 long distance minutes in September
You start with $85-$60 which is just subtracting the monthly bill, that equals $25. Then you would divide $25 by the amount for each minute ($0.10), that equals 250. Therefore he made 250 long distance calls.
