\n" ); document.write( "A piggy bank contains \"30+coins\" ,all nickels \"n\" and dimes \"d\".\r
\n" ); document.write( "\n" ); document.write( "so, \"n%2Bd=30\"\r
\n" ); document.write( "\n" ); document.write( "if there are \"4\" times as many nickels as dimes, then \"4n=d\"\r
\n" ); document.write( "\n" ); document.write( "substitute in \"n%2Bd=30\"\r
\n" ); document.write( "\n" ); document.write( "\"n%2B4n=30\"....solve for \"n\"\r
\n" ); document.write( "\n" ); document.write( "\"5n=30\"\r
\n" ); document.write( "\n" ); document.write( "\"n=30%2F5\"\r
\n" ); document.write( "\n" ); document.write( "\"n=6\"\r
\n" ); document.write( "\n" ); document.write( "find dimes\r
\n" ); document.write( "\n" ); document.write( "\"4%2A6=d\"\r
\n" ); document.write( "\n" ); document.write( "\"d=24\"\r
\n" ); document.write( "\n" ); document.write( " the total value of the coins: where nickel \"n=5\" cents and dime \"d=10\" cents\r
\n" ); document.write( "\n" ); document.write( "\"24%2A10%2B6%2A5=240%2B30=270\" cents
\n" ); document.write( "
\n" ); document.write( "
