telephone service costs 30.00 per month plus .15 for each local call.
last month the bill was 63.50
it included 18.50 in long distance charges.
how many local calls ere made.

monthly bill was 63.50 minus 30 per month for fixed charges minus 18.50 for long distance calls.
cost for locals was therefore 63.50 - 30 - 18.50 = 15.00.
at .15 per local call, the number of local calls was 15.00 / .15 = 100.

100 should be your answer.

total charges for the month were 30 for the fixed charges plus 18.50 for the long distance charges plus 100 * .15 = 15.00 for the local calls.

total bill was 30.00 + 18.50 + 15.00 = 63.50.

this confirms the value for the number of local calls is correct.
