Subtract 8 feet from 9 yards, 1 foot.
Nostrana [21]

Answer: B

Step-by-step explanation:

I knew I would have 1 foot left so that made sure it wasn’t A then I knew that it the answer had to be in yards so I convert 8 feet into yards which becomes 2.7 so it’s not three which makes I’m not C. So 9 yards minus 2.7 yards would equal the answer B
