Let

X1X_1 represent chairs and X2X_2 represent tables


Maximize:z=2x1+10x2Maximize: z=2x_1 ​+10x_2\\


Subject to;

2x1+5x2166x130​2x_1 ​+5x_2 ​≤16\\6x_1 ​≤30


As represented in the graph below, the points that satisfies the constraints is given by ;

(0,165),(5,65)(0,\frac{16}{5}),(5,\frac{6}{5})

We input both points into the objective function, we have that (0,165)(0,\frac{16}{5})gives the the maximum value, hence no chair should be produced and approximately 4 tables should be produced
