rainfall findings
amount of rainfall for the month: 0.75 in.
compared to average amount of rainfall for the month: -0.55 in.

what was the average amount of rainfall, in inches, for this month during the last ten years?
enter answer here:

Explanation:

Step1: Define the relationship

Let \( x \) be the average rainfall. The current rainfall (0.75 in) is 0.55 in below the average, so the equation is \( x - 0.55 = 0.75 \).

Step2: Solve for \( x \)

To find \( x \), add 0.55 to both sides of the equation: \( x = 0.75 + 0.55 \).

Step3: Calculate the sum

\( 0.75 + 0.55 = 1.3 \).

Answer:

1.3
