I really don't understand this...
Please help?
3) A solution containing 30% insecticide is to be mixed with a solution containing 50% insecticide to make 200 liters of a solution that is 42% insecticide. How much of the 30% solution can you use?
4) A 50 gallon barrel of milk is 4% butterfat. How much skim milk must be added to make a milk that is 1% butterfat?
5) A candy store mixes plain and peanut m&ms. The plain cost $2.50 per pound and the peanut cost $3.00 per pound. How many of each should they mix to make a 5 pound mixture that they can sell for $2.70 per pound.
Even helping me out with one problem would be great.
thanks!
