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)
