\"A pharmacist needs 6 oz of a 30% codeine solution\" Of refering to the product:
\n" ); document.write( "Let the solution be x
\n" ); document.write( "Equation:
\n" ); document.write( "20x+50(6-x)=30(6)
\n" ); document.write( "20x+300-50x=180
\n" ); document.write( "-30x=-120
\n" ); document.write( "x=4
\n" ); document.write( "6-4=2
\n" ); document.write( "Hence, he needs 4 oz of 20% and 2 oz of 50%.
\n" ); document.write( "Paul. \n" ); document.write( "
