A pharmacist is to prepare a 50 fluid ounce solution that contains 54% glucose. The pharmacy has a 30% solution and a 90% solution on hand. How many ounces of each solution should be mixed to prepare the desired prescription?
\n" ); document.write( "--------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "glucose + glucose = glucose
\n" ); document.write( "0.30x + 0.90(50-x) = 0.54*50
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "30x + 90*50 - 90x = 54*50
\n" ); document.write( "-60x = -36*50
\n" ); document.write( "---
\n" ); document.write( "x = (5/6)(36)
\n" ); document.write( "x = 30 fluid ounces (amt. of 30% solution needed for the mixture)
\n" ); document.write( "---
\n" ); document.write( "50-x = 20 fluid ounces (amt. of 90% solution needed for the mixture)
\n" ); document.write( "===========================================
