A silversmith mixes 60g of alloy that is 50% silver with 200g of another silver alloy. the resulting alloy is 65% silver. find the percent of silver in the 200g of alloy. \n" ); document.write( "--------- \n" ); document.write( "Equation: \n" ); document.write( "silver + silver = silver \n" ); document.write( "0.50*60 + r*200 = 0.65*(60+200) \n" ); document.write( "----- \n" ); document.write( "Multiply thru by 100 to get: \n" ); document.write( "50*60 + 200r = 65*60 + 65*200 \n" ); document.write( "---- \n" ); document.write( "(r-65)200 = 15*60 \n" ); document.write( "--- \n" ); document.write( "r-65 = 4.5 \n" ); document.write( "r = 69.5% (% of silver in the 200g of alloy) \n" ); document.write( "============================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
