Question 1058032
Look at the number of resistors used,
{{{20A+10B<=200}}}
Look at the number of transistors used,
{{{10A+20B<=120}}}
Look at the number of capacitors,
{{{10A+30B<=150}}}
Finally look at the profit function,
{{{P=5A+12B}}}
Graph the feasible region,

Check the profit function at each of the vertices,
(0,5): {{{P=5(0)+12(5)=60}}}
(6,3): {{{P=5(6)+12(3)=30+36=66}}}
(28/3,4/3): {{{P=5(28/3)+12(4/3)=140/3+48/3=188/3}}}
(10,0): {{{P=5(10)+12(0)=50}}}

{{{P[max]=66}}}
{{{A=6}}}
{{{B=3}}}
