Final answer:
Kennedy should buy 42 sets of spoons, as she needs a minimum of 512 spoons to meet the restaurant's needs and each set contains 6 spoons.
Step-by-step explanation:
Kennedy needs to calculate the minimum number of spoon sets to buy, given that the restaurant needs at least 512 spoons and there are currently 264 spoons. Each set contains 6 spoons. To solve this, Kennedy should first determine how many additional spoons are needed by subtracting the existing spoons from the total required spoons:
512 spoons needed - 264 spoons available = 248 spoons required.
Next, she would calculate the number of sets needed by dividing the spoons required by the number spoons per set:
248 spoons required / 6 spoons per set = 41.333 sets.
Since Kennedy cannot buy a fraction of a set, she needs to round up to the nearest whole number, so the minimum number of sets Kennedy needs to buy is:
42 sets.
