i tried 1.40x + 3(2.20) = $1.64 but this doesn't work. the answer is 7 pounds but i don't understand how to get the formula. Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 2.20*3+1.40X=1.64(3+X) OR 6.60+1.40X=4.92+1.64X OR 1.68=.24X OR X=1.68/.24 OR X=7 POUNDS OF $1.40 NUTS
