an equation form $\"30\"$ more quarters and nickels?\r
\n" ); document.write( "\n" ); document.write( "I assume there is $\"30\"$ more quarters than nickels\r
\n" ); document.write( "\n" ); document.write( "let the number of quarters be $\"x\"$ and the number of nickels be $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=y%2B30\"$ ....eq.1\r
\n" ); document.write( "\n" ); document.write( "$ $\"q=0.25\"$
\n" ); document.write( "$ $\"n=0.05\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"0.25x%2B0.05y=73.50\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.25%28y%2B30%29%2B0.05y=73.50\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.25y%2B7.5%2B0.05y=73.50\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.30y=73.50-7.5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.30y=66\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=66%2F0.30\"$ \r

\n" ); document.write( "\n" ); document.write( " $\"x=250\"$ \r
\n" ); document.write( "\n" ); document.write( "so, you have $\"250\"$ quarters and $\"220\"$ nickels\r
