A. Plastic party spoons
Number of packages = 150 / 24
Number of packages = 6.25
Since we must ensure that each guest gets 1 spoon, so we cannot round the number to a lower number. Hence the correct answer is 7 packages.
Answer: C. 7
B. Dry dog food
Number of bags = 450 / 40
Number of bags = 11.25
Since the problem only ask about how many bags were full, so the correct answer is 11.
Answer: 11
