Jeremy's Graphics uses one cleanser that is 25% acid and a second that is 50% acid. How many liters of each must be mixed together to produce 10 liters that is 40% acid?
\n" ); document.write( "---------------------
\n" ); document.write( "Quantity Eq:: t + f = 10 liters
\n" ); document.write( "Acid Eq::::: 25t+50f = 45*10
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "25t + 25f = 250
\n" ); document.write( "25t + 50f = 450
\n" ); document.write( "--------------------
\n" ); document.write( "25f = 200
\n" ); document.write( "f = 8 liters (amt. of 50% solution needed)
\n" ); document.write( "-------------------------
\n" ); document.write( "Solve for \"t\":
\n" ); document.write( "t + f = 10
\n" ); document.write( "t + 8 = 10
\n" ); document.write( "t = 2 liters (amt of 25% solution needed)
\n" ); document.write( "==================
