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?
\n" ); document.write( "----------
\n" ); document.write( "Equation:
\n" ); document.write( "juice + juice = juice
\n" ); document.write( "0.10(1) + 1*x = 0.40(1+x)
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "10 + 100x = 40 + 40x
\n" ); document.write( "60x = 30
\n" ); document.write( "x = 1/2 litre (amt. of 100% juice needed in the mixture)
\n" ); document.write( "======================
