In a northwestern town, it rained 4 inches per day during the first 15 days of November. For the remainder of the month, the average daily rainfall was twice the amount observed during the first 15 days. What is the total amount of rainfall for this town in November, in inches? Let's answer step by step:
Since November has 30 days, the town received 4 inches of rain for the first half of the month for 30 / 2 = 15 days. The total inches of rain that the town received for the 15 days is 15 * 4 = 60 inches. The rain falling in the town increased by 2 * 4 = 8 inches per day for the remaining half of the month. Therefore, for the rest of the month, the town received 8 * 15 = 120 inches of rain. The total amount of rain the town received in November is 120 + 60 = 180 inches. The answer: 180.
