We know that you need to wirte a essay that has at least 500 words.
If you have written 285 words, to find the number of words that you have left to write we can use an inequality
[tex]\begin{gathered} 285+w\ge500 \\ \end{gathered}[/tex]Finally, we must solve the inequality for w
[tex]\begin{gathered} 285+w\ge500 \\ w\ge500-285 \\ w\ge215 \end{gathered}[/tex]So, you have left to write at least 215 words.
