Final answer:
Sally bought 3.52 pounds more cheese than Dan. We found this by subtracting the amount Dan bought from the amount Sally bought.
Step-by-step explanation:
The student is asking how much more cheese Sally bought than Dan. We have to subtract the amount of cheese Dan bought from the amount Sally bought. Sally bought 6.77 pounds and Dan bought 3.25 pounds. We subtract as follows: 6.77 - 3.25 = 3.52. So Sally bought 3.52 pounds more cheese than Dan. This makes option b) the correct answer.
