Number of long distance calls made = m
Total phone bill = $3.40 = 340 cents
Cost per minute for long distance call = 3.3 cents
Then
3.3m = 3.40
On solving we get
m = 340/3.3
    = 103 minutes

From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the first option. I hope the answer has come to your help.
