Answer:
Norma rainfall for the area = 22*2 = 44 inches
Step-by-step explanation:
So because the rainfall last year was 50% below normal, this means that it was half of what is known as the normal rainfall (percentage total is equal to a 100%, so 50% is half of it).
So since you know that 22 inches is 50% of the normal value, that means a 100% of the normal value will be 22*2 = 44 inches.
