9. If a new roll of electrical wire was \( 25^{\prime} \) long, and Scott cut \( 32^{\prime \prime} \) off of it, how much wire remains?

To determine how much electrical wire remains after Scott cuts off \( 32'' \) from a \( 25' \) roll, follow these steps: 1. **Convert All Measurements to the Same Unit** It's easier to perform the calculation if both measurements are in the same unit. We'll convert feet to inches since the amount cut is given in inches. \[ 1 \text{ foot} = 12 \text{ inches} \] \[ 25' = 25 \times 12'' = 300'' \] 2. **Subtract the Cut Length from the Total Length** \[ \text{Remaining Wire} = \text{Total Length} - \text{Cut Length} \] \[ \text{Remaining Wire} = 300'' - 32'' = 268'' \] 3. **Convert the Remaining Length Back to Feet and Inches (Optional)** To express \( 268'' \) in feet and inches: \[ 268'' \div 12 = 22 \text{ feet } \text{ with a remainder of } 4'' \] So, \[ 268'' = 22' \, 4'' \] **Final Answer:** After cutting off \( 32'' \), Scott has **268 inches** of electrical wire remaining, which is equivalent to **22 feet 4 inches**.
