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:
\[ 1170.5616 \approx 1200 \]
