\n" ); document.write( "Cameron has 45 coins, all dimes and quarters. The total value of the coins is $9.15.
\n" ); document.write( " How many dimes?
\n" ); document.write( " How many Quarters?
\n" ); document.write( " Thank you!
\n" ); document.write( "

Let number of dimes be D
\n" );
document.write( "Then number of quarters is: 45 - D
\n" );
document.write( "We then get the following VALUE equation: .1D + .25(45 - D) = 9.15
\n" );
document.write( ".1D + 11.25 - .25D = 9.15
\n" );
document.write( ".1D - .25D = 9.15 - 11.25
\n" );
document.write( "- .15D = - 2.1
\n" );
document.write( "D, or number of dimes = 
\n" );
document.write( "Number of quarters:  \n" );
document.write( "

\n" );
