Answer: A. $35.10
Explanation:
Since the total money paid for the water for 3months is $95 and there are 31 days in October, 30days in November and 31 days in December totalling 92days. Therefore $95 was charged for water for 92days.
Since the owner sold the house and the rentage stopped 27th November, this shows the person only used water for (31+27) days i.e 58 days in the house.
The amount that will be received by the owner upon closing will be;
Since 92days of water used is equivalent to $95
58days will be equivalent to 58×95/92 = $59.9
The amount received will be
95-59.9 = $35.10 (A)
