Final answer:
The average rainfall for the month is calculated by dividing the total rainfall of 23.6 inches by 2.5, which represents 250% expressed as a decimal, resulting in an average of 9.44 inches.
Step-by-step explanation:
To calculate the average monthly rainfall when given that 23.6 inches is 250% of the average, we must first understand that 250% is the same as 2.5 times the average. Therefore, we divide 23.6 inches by 2.5 to find the average rainfall.
Step-by-step calculation:
- Express 250% as a decimal: 250% = 2.5.
- Divide the total rainfall by this decimal to find the average: 23.6 inches ÷ 2.5 = 9.44 inches.
So, the average rainfall for that month is 9.44 inches.
