If receptacles are placed around a 24-by-24 building every 12 feet, and each receptacle costs $35, what is the total cost?

Explanation:
Think about how many receptacles fit around the outside of the square building. The perimeter is 4 sides × 24 ft = 96 ft. If you place one receptacle every 12 ft, you’ll have 96 ÷ 12 = 8 receptacles around the loop. With each receptacle costing $35, the total cost is 8 × 35 = $280.
