Give the step-by-step reasoning process and then the final answer. Emily wants to know how much it rained last week. She sees that it rained 2 inches on Monday morning and 1 more inch later that day. It rained twice that much on Tuesday. It did not rain on Wednesday but on Thursday it rained 1 inch. The biggest storm was on Friday when the total was equal to Monday through Thursday combined. What was the daily average rain total for the week?
The total rain was 2 inches + 1 inches = 3 inches on Monday. The total rain was 2 * 3 inches = 6 inches on Tuesday. The total rain was 0 inches + 1 inch = 1 inch across Wednesday and Thursday. The total rain was 3 inches + 6 inches + 1 inch = 10 inches on Friday. There were 3 inches + 6 inches + 1 inch + 10 inches = 20 inches total last week. 20 inches / 5 days = 4 inches average daily rain.
The final answer: 4.
