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 = <<2+1=3>>3 inches on Monday.
The total rain was 2 * 3 inches = <<2*3=6>>6 inches on Tuesday.
The total rain was 0 inches + 1 inch = <<0+1=1>>1 inch across Wednesday and Thursday.
The total rain was 3 inches + 6 inches + 1 inch = <<3+6+1=10>>10 inches on Friday.
There were 3 inches + 6 inches + 1 inch + 10 inches = <<3+6+1+10=20>>20 inches total last week.
20 inches/5 days = <<20/5=4>>4 inches average daily rain.
