You can put this solution on YOUR website! A certain orange beverage contains only 10% juice. How much juice has to be added to one litre of this drink so that the new mixture will contain 40% juice?
----------
Equation:
juice + juice = juice
0.10(1) + 1*x = 0.40(1+x)
Multiply thru by 100 to get:
10 + 100x = 40 + 40x
60x = 30
x = 1/2 litre (amt. of 100% juice needed in the mixture)
