Question 125248: AN HEBALIST HAS 30 OZ OF HERBS COSTING $2 PER OUNCE. HOW MANY OUNCES OF HERBS COSTING $1 PER OUNCE SHOULD BE MIXED WITH THE 30 OZ TO PRODUCE A MIXTURE COSTING $1.60 PER OUNCE? Answer by dolly(163) (Show Source):
You can put this solution on YOUR website! let x ounces of herbs costing $1 be added.
Then 30(2) + (x)(1) = (30+x)(1.6)
==> 60 + x = 48 + 1.6x
==> 60 - 48 = 1.6x - x
==> 12 = 0.6x
==> 12/0.6 = x
==> x = 20
Thus 20 ounces cosing $1 need to be added,
Good luck
