You can put this solution on YOUR website!
L = 7.8 dollars per pound
H = 8.1 dollars per pound
T = 7.86
M = 20 pounds for the blend
p, how many pounds of the $8.10 coffee


L%28M-p%29%2BHp=TM
-
LM-Lp%2BHp=TM
%28H-L%29p=TM-LM
highlight_green%28p=M%28%28T-L%29%2F%28H-L%29%29%29

-----substitute given values -------
p=20%28%287.86-7.8%29%2F%288.1-7.8%29%29
highlight%28p=4%29 and the other quantity is 16 pounds.
