    Code:
    3x + 2y = 200
    1,5x + y -100 = 0
    y = 100 - 1,5x
    
    A = x(100-1,5x)
    
    -1,5x^2 +100x = 0
    
    Peak of parabola func A(x) is in point [p,q]
    
     { p = -b/2a }
    
    p = -100/-3 = 33,3(3)  == x for max A
    
    so:
    y = 100 - 1,5x = 100 - 1,5*33,3(3) =~ 50

    Oh boy, I just had a test on optimization problems last month, I already forgot how to do them...

    I actually have a test tomorrow on Integrals and Summation, both of which I find easier than optimization was.

    Honesty I found Optimization and Related Rates hard at first (didn't pay attention in class), but now I'm like psshh that's easy stuff.
