Explanation:

Read values from the graph

Identify the departure value for each month.

• May: \(+3.0\text{ in}\)
• June: \(-1.0\text{ in}\)
• July: \(+1.5\text{ in}\)
• August: \(+4.0\text{ in}\)
• September: \(-2.5\text{ in}\)

Sum the monthly departures

Using the Order of Operations knowledge point:

$$ \text{Total} = 3.0 + (-1.0) + 1.5 + 4.0 + (-2.5) $$

Calculate the final sum

Combine positive and negative values.

$$ \text{Total} = (3.0 + 1.5 + 4.0) + (-1.0 - 2.5) = 8.5 - 3.5 = 5.0\text{ in} $$

Determine above or below average

Since the total departure is positive, it is above average.

$$ 5.0 > 0 \implies \text{Above average} $$

Answer:

The total departure from average is \(5.0\text{ inches}\). The total rainfall for these months is above average.
