Final answer:
Violet could buy at least 134 sets of glasses for the restaurant to have enough.
Step-by-step explanation:
To determine the number of sets of glasses Violet could buy for the restaurant to have enough glasses, we need to set up an inequality. Let x be the number of sets of glasses. Since each set contains 6 glasses, the total number of glasses that Violet could buy is 6x. The restaurant needs at least 800 glasses, so the inequality is:
6x ≥ 800
To solve this inequality, divide both sides by 6:
x ≥ 800 ÷ 6
x ≥ 133.33
Since x represents the number of sets of glasses, it must be a whole number. Therefore, Violet could buy at least 134 sets of glasses for the restaurant to have enough.
