When I enter this:
n=50, B=150, k=29.5, h=13.5, x=floor(B/k), H=(ceil(n/(2*x))*h)
I get a solution:
B = 150, h = 27/2, H = 135/2, k = 59/2, n = 50, x = 5
BUT when I enter this:
n=50, B=150, R=2, k=29.5, h=13.5, x=floor(B/k), H=(ceil(n/(R*x))*h)
I get an error:
Wolfram|Alpha doesn't understand your query
Why?
