Question 165629
{{{A + B <= 100}}}
{{{50A + 40B >= 4400}}}
Lets solve the first equation for either A or B;
B = 100-A
Now plug this into the second equation for b;
{{{50A + 40(100-A) >= 4400}}}
{{{50A + 4000-40A >= 4400}}}
{{{10A + 4000 >= 4400}}}
{{{10A >= 400}}}
{{{A >= 40}}}
Now we have A, lets plug that into the first equation;
{{{40 + B <=100}}}
{{{B<= 60}}}
check;
{{{50(40)+ 40(60)>= 4400}}}
{{{2000+2400>=4400}}}
