For his long distance phone service, frank pays and $8 monthly fee plus 6 cents per minute. Last month, frank's long distance bill was $14.06. For how many minutes was frank billed?

Frank was billed for 101 minutes

Step-by-step explanation:

Let x represent the number of minutes for which Frank was billed.

For his long distance phone service, frank pays and $8 monthly fee plus 6 cents per minute. It means that the total amount that he would pay for x minutes in a month is

8 + 0.06x

Last month, Frank's long distance bill was $14.06. It means that

8 + 0.06x = 14.06

0.06x = 14.06 - 8

0.06x = 6.06

x = 6.06/0.06

x = 101 minutes
