Noah needs to order some new supplies for the restaurant where he works. The restaurant needs at least 503 knives. There are cur
rently 391 knives. If each set on sale contains 10 knives, which inequality can be used to determine xx, the minimum number of sets of knives Noah should buy?
If you need at least 503 knives, both the sets of knives and the initial amount we already have (391) must add to have a number of knives greater than or equal to the minimum required amount.
