The actual rainfall for last June is 0.5
1.14 is the amount of rain that fell last July.
2.43 is how much rain would have to fall for August to match the three months average
0.86 is the departure from the average in August
Step-by-step explanation:
1. 0.67-0.17 = 0.5
2. 1.5-0.36 = 1.14
Step-by-step explanation:
a) 0.5 inches. The difference between the average rainfall and the actual rainfall for last June is 0.67-0.17=0.50 inches.
b) 1.14 inches. Because the departure from the average was negative, the actual rainfall was 0.36 inches less than the average rainfall. Thus, 1.5-0.36=1.14 inches was the actual rainfall last July.
c) 2.43 inches. The average rainfall for these three months is 0.67+1.5+1.57=3.74 inches. Last June it rained 0.17 inches and last July it rained 1.14 inches. So, it would need to have rained 3.74-0.17-1.14=2.43 inches last August so that the total amount of rain equaled the average rainfall for these three months.
0.86 inches. The departure from the average would then be 0.86 inches since 2.43-1.57=0.86 inches.
Merry Christmas
