Final answer:
To find the total charges, you multiply 120 minutes by $0.15/minute and add this to the monthly charge of $33.95, which equals $51.95. Therefore, the correct option is (c) $51.95.
Step-by-step explanation:
If a long distance phone company charges $33.95 per month, plus an additional $0.15 per minute for phone calls, and you make 120 minutes of calls in a month, the total charges are calculated as follows:
Monthly Charge = $33.95 (flat rate)
Per Minute Charge = 120 minutes × $0.15/minute
= $18.00
Therefore, the total charges for the month would be:
$33.95 + $18.00 = $51.95
So, the correct answer is (c) $51.95.
