In a house where 35 outlets are installed, 735 feet of cable are used. What is the average number of feet of cable used per outlet?

• A. 20 feet
• B. 21 feet
• C. 22 feet
• D. 23 feet

Answer: (B)

Dividing the total length by the number of outlets gives the average per outlet. So, 735 feet of cable for 35 outlets means 735 ÷ 35. Since 35 × 21 = 735, the division yields 21. Therefore, the average is 21 feet of cable per outlet.
