Final answer:
Manuel has 8.25 pounds of apples left.
Step-by-step explanation:
To find out how many pounds of apples Manuel has left, we need to subtract the amount he has eaten from the total amount he bought. Manuel bought 9 pounds of apples and has eaten 3/4 of a pound so far. To subtract 3/4 from 9, we can convert 3/4 to a decimal by dividing 3 by 4, which equals 0.75. Then, we can subtract 0.75 from 9 to find that Manuel has 8.25 pounds of apples left. Therefore, the correct answer is B) 8.25 pounds.
