The solution is:
[tex]x\ge6[/tex]Explanation:
Representing the given scenario, we have:
5500 + 300x
where x is the number of workers.
To generate at least $7,300, then
[tex]5500+300x\ge7300[/tex]Solving the inequality above, we have the number of workers that er require.
[tex]\begin{gathered} 300x\ge7300-5500=1800 \\ x\ge\frac{1800}{300}=6 \end{gathered}[/tex]The solution is:
[tex]x\ge6[/tex]This is demonstrated below:
