You can put this solution on YOUR website!
Let x = number of quarters. The rest of the 103 coins are dimes, so
\n" ); document.write( "103 - x = number of dimes.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order to work the whole problem in cents, change the $15.25 to cents: 1525 cents.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Value of quarters + value of dimes = Total value of coins
\n" ); document.write( "25(x) + 10(103 - x) = 1525
\n" ); document.write( "25x + 1030 - 10x = 1525
\n" ); document.write( "15x + 1030 = 1525
\n" ); document.write( "15x + 1030 - 1030 = 1525 - 1030
\n" ); document.write( "15x = 495\r
\n" ); document.write( "\n" ); document.write( "\"15x%2F15+=+495%2F15\"
\n" ); document.write( "\"x+=+33\" Quarters\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Number of dimes
\n" ); document.write( "= 103 - x
\n" ); document.write( "= 103 - 33
\n" ); document.write( "= 70 Dimes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check: Total value = $15.25
\n" ); document.write( "Quarters .25(33) = $8.25
\n" ); document.write( "Dimes .10(70) = 7.00
\n" ); document.write( "Total = $15.25\r
\n" ); document.write( "
