A collection of nickels, dimes and quarters consists of 22 coins with a total value of $1.75. If the number of nickels is three times the number of dimes, how many of each coin are contained in the collection?
\n" ); document.write( "

Let number of dimes be D
\n" );
document.write( "Then number of nickels = 3D, and number of quarters = 22 - (D + 3D) = 22 - 4D
\n" );
document.write( "We then get: .1D + .05(3D) + .25(22 - 4D) = 1.75
\n" );
document.write( ".1D + .15D + 5.5 - D = 1.75
\n" );
document.write( "- .75D = - 3.75
\n" );
document.write( "Number of dimes, or 
\n" );
document.write( "The number of nickels and quarters are now easy to find! \n" );
document.write( "

\n" );
