Note: Your question is not clearly explained. But it seems you may have been asking EITHER

Scenario 1:  To find the values of and when the value of n = 8. So, I am solving based on this scenario.

OR

Scenario 2: To find when   and .

So, I solving both scenarios.

Step-by-step explanation:

SOLVING SCENARIO 1

To find the values of and when the value of n = 8. So, I am solving based on this scenario.

Considering the functions

Putting n = 8

Putting n = 8

SOLVING SCENARIO 2

To find  when   and .

So, I solving both scenarios.

step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
