Answer 1

To determine how many feet of fabric were remaining after a customer bought 3 feet of fabric from a 144-inch roll, we can follow these steps:

1. **Convert the length of the fabric from inches to feet:**
- The roll of fabric is 144 inches long.
- Since 1 foot = 12 inches, we can convert inches to feet by dividing by 12:
\[
\text{Length in feet} = \frac{144 \text{ inches}}{12 \text{ inches/foot}} = 12 \text{ feet}
\]

2. **Subtract the length of fabric bought by the customer:**
- The customer bought 3 feet of fabric.
\[
\text{Remaining fabric} = 12 \text{ feet} - 3 \text{ feet} = 9 \text{ feet}
\]

Thus, the amount of fabric remaining is 9 feet.

The answer is **B. 9**.
