Number of glasses Victoria need to buy for restaurant are at least 31 from the inequality given by 10x + 368 ≥ 673.
As given in the question,
Number of glasses required in the restaurant at least 673.
Number of glasses currently available in the restaurant = 368
Number of glasses in each set used to sale = 10
Let 'x' represent the number of sets of the glasses Victoria need to buy.
Required inequality is given by :
10x + 368 ≥ 673
⇒ 10x + 368 - 368 ≥ 673 - 368
⇒ 10x ≥ 305
⇒ x ≥ 30.5
Number of sets bought by Victoria = At least 31
Therefore, from the inequality 10x + 368 ≥ 673 the number of sets of glasses bought by Victoria is equal to at least 31.
