The Divine Chocolate store want to create a new truffle mix that consists of milk chocolate and hazelnut. If hazelnuts sell for $2 per pound and milk chocolate sells for $4 per pound, how many pounds of each should they mix together to create a 18-pound box that sells for $3 per pound?
A chemist wants to mix a 60% alcohol solution with 9 liters of a 66% alcohol solution to produce a solution that is 62% alcohol. How many liters of the 60% alcohol solution should be used?

You can put this solution on YOUR website! The Divine Chocolate store want to create a new truffle mix that consists of milk chocolate and hazelnut. If hazelnuts sell for $2 per pound and milk chocolate sells for $4 per pound, how many pounds of each should they mix together to create a 18-pound box that sells for $3 per pound?
let x = number of pounds of hazelnut.
let y = number of pounds of mixed chocolate.
you know that the total pounds has to be 18, so x + y = 18
you know that the total money to be earned is 3 dollars a pound times 18 pounds = 54 dollars.
you know that hazelnuts cost 2 dollars a pound and mixed chocolates cost 4 dollars a pound.
therefore 2x + 4y = 54
the two equations that you have to solve simultaneously are:
2x + 4y = 54
x + y = 18
work it out and see what you get.
don't forget to confirm if you answer is correct.
