Answer:
7.83 inches of rain.
Step-by-step explanation:
In order to solve this problem you just have to add up all the values that you are given for the daily rain of the week:
First day: 3 in
Second day: 0.58 in + 3in= 3.58 in
Third day: 0 in + 3.58 in=3.58 in
Fourth day: 1.2 in + 3.58 in= 4.78 in
Fifth day: 0 in +4.78 in= 4.78 in
Sixth day: .9 in +4.78 in= 5.68 in
Seventh day: 2.15 in +5.68 in= 7.93 in
So the total rain that fell during the week was 7.93 inches of rain.
