Hi there!
First, let's figure out how many feet are in the total amount of tape. This can be done by multiplying the amount of yards (4) and multiplying it by the amount of feet in a yard (3). This gives us 12 feet. Then, we need to subtract the amount of feet that are left (2). This gives us 10 feet.
ANSWER:
B - 10 feet
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
