Question

Kevin needs to order some new supplies for the restaurant where he works. The restaurant needs at least 491 glasses. There are currently 333 glasses. If each set on sale contains 18 glasses, which inequality can be used to determine x x x, the minimum number of sets of glasses Kevin should buy?

Answer 1

9 sets of glasses

Explanation:

If Kevin needs 491 glasses and he already has 333 glasses, this means he only needs 158 glasses. If each case has 18 glasses you can make the equation 18x = 158 and to get x by itself you would divide 158 by 18 to get 8.7 and since you have to buy the cases as sets of 18, you would need 9 sets.
