Question 1057022: An herbalist has 30 oz of herbs costing $3 per ounce. How many ounces of herbs costing $2 per ounce should be mixed with these 30 oz of herbs to produce a mixed costing $2.50 per ounce? Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! 3(30)+2(x) = 2.50(30+x)
90+2x = 75+2.50x
-0.50x = -15
x = 30
You need 30oz of 2 to mix with the 30oz of 3 to get a mix at 2.50
