Tropical Storm Sally brings 3 days of rain to southern Texas. The first day it rained 4 inches. The second day it rained 5 times as much as the first day, and the third day it rained 6 inches less than the sum of the first two days. How much did it rain on the third day? Give me reasons, before answering the question

First Day:4 inches. Second Day: 5(4) = 20 inches. Third Day: (4 + 20) - 6 = 18 inches. So the final answer is 18.
