Question

In 1 month it rained 12 inches. Then it rained 3 inches per month for 9 months. How many inches did it rain in all?

Answer 1

Answer: 39

Step-by-step explanation: Just addition

Answer 2

Total rainfall = 39 inches.

Explanation:

The question is not properly qualified. I am assuming that the first month, 12 inches of rain fell (that is an awful lot) and for the next 9 months the rainfall was 3 inches per month.

Let R be the total rainfall.

R = first month + 9*3

R = 12 + 27

R = 39
