The given inequality is:
[tex]600-n>465[/tex]Subtract 600 from both sides
[tex]\begin{gathered} 600-n-600>465-600 \\ -n>-135 \end{gathered}[/tex]Multiply both sides by -1 and change the inequality:
[tex]\begin{gathered} (-1)(-n)>(-1)(-135) \\ n<135 \end{gathered}[/tex]The inequality is true for n-values less than 135.
