Algebra.Com's Answer #646192 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! a solution of 72% fertilizer is to be mixed with a 26% fertilizer to form 230 liters of a 53% solution. How many liters of the 72% solution must be used \n" ); document.write( "------ \n" ); document.write( "Quantity:: s + t = 230 liters \n" ); document.write( "Fertilizer: 0.72s + 0.26t = 0.53*230 \n" ); document.write( "-------------------------------------------- \n" ); document.write( "Modify for elimination:: \n" ); document.write( "26s + 26t = 26*230 \n" ); document.write( "72s + 26t = 53*230 \n" ); document.write( "-------------------------------- \n" ); document.write( "Subtract and solve for \"s\":: \n" ); document.write( "46s = 27*230 \n" ); document.write( "s = 135 liters (amt. of 72% solution needed) \n" ); document.write( "------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------- \n" ); document.write( " |
