Question 1035818: How many ounces of mixed nuts that contain 20% peanuts must Jose add to 11 ounces of mixed nuts that contain 70% peanuts to make a mixture with 42% peanuts Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let n = your first mixture
.2(n)+.7(11)=.42(n+11)
.2n+7.7=.42n+4.62
.22n=3.08
n=14
14 ounces of 20% peanuts must be mixed with 11 ounces of 70% peanuts to get a mixture of 42% peanuts, in 25 ounces!!!!!!!!!!!!!!!
