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.
