What are inequalities?
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Let the number of sets of knives indigo should buy be represented by x.
Given Indigo needs to order some new supplies for the restaurant where she works and the restaurant needs at least 430 knives. Also, There are currently 269 knives. Now, If each set on sale contains 18 knives the inequality that can represent the minimum number of sets of knives Indigo should buy is,
269+18x≥430
18x≥430-289
18x≥141
x≥7.833
x≥8
Hence, the minimum number of sets of knives Indigo should buy is 8.
