Solution

Solution Steps

Step 1: Identify the percentage for heating and cooling

From the pie chart, heating and cooling account for 48% of the total home energy expenditure.

Step 2: Calculate the amount spent on heating and cooling

Multiply the total home energy expenditure by the percentage for heating and cooling: \[ \text{Amount spent on heating and cooling} = 2438.67 \times 0.48 \]

Step 3: Perform the multiplication

\[ 2438.67 \times 0.48 = 1170.5616 \]

Step 4: Round to the nearest hundred

Round 1170.5616 to the nearest hundred: \[ 1170.5616 \approx 1200 \]
