Explanation:
The number of standard ranges is represented as
[tex]x[/tex]The number of delux ranges is represented as
[tex]y[/tex]Hence,
The objective constraint will be
[tex]P=50X+60Y[/tex]The constraints will be given below as
[tex]\begin{gathered} 0\leq X\leq500 \\ 0\leq Y\leq400 \\ X+Y\leq600 \end{gathered}[/tex]
