The problem in the image involves converting feet to inches and performing a subtraction.

**Problem Summary:**
- A plumber has an 8-foot piece of copper pipe.
- He needs to cut a 3-foot, 10-inch piece for the repair.
- We need to find out how many inches of pipe he will have left.

### Steps:
1. **Convert the measurements to inches:**
   - 1 foot = 12 inches.
   - The plumber's pipe is 8 feet long:  
     \[ 8 \text{ feet} = 8 \times 12 = 96 \text{ inches} \]
   - The piece he cuts is 3 feet 10 inches:  
     \[ 3 \text{ feet} = 3 \times 12 = 36 \text{ inches} \]
     \[ 3 \text{ feet 10 inches} = 36 + 10 = 46 \text{ inches} \]

2. **Subtract the cut piece from the total:**
   \[ 96 \text{ inches} - 46 \text{ inches} = 50 \text{ inches} \]

### Answer:
The plumber will have **50 inches** of copper pipe left.
