Explanation:

Calculate total floor area

Find the sum of the glass and brick floor areas.

$$ A_{\text{total}} = 6700 + 1048 = 7748\text{ sq ft} $$

Find occupied floor area

Using the Fraction Multiplication knowledge point

$$ A_{\text{occupied}} = 7748 \times \frac{1}{2} = 3874\text{ sq ft} $$

Calculate average area per store

Using the Unit Rate knowledge point

$$ A_{\text{average}} = \frac{3874}{13} = 298\text{ sq ft} $$

Answer:

• A. 150
• B. 298 (Correct answer)
• C. 325
• D. 400
