Write an equation for each phrase/statement
\n" ); document.write( ":
\n" ); document.write( "A group of twenty-five coins, composed of nickels, dimes, and quarters.
\n" ); document.write( "n + d + q = 25
\n" ); document.write( ":
\n" ); document.write( " whose total value is $2.75,
\n" ); document.write( ".05n + .10d + .25q = 2.75
\n" ); document.write( ":
\n" ); document.write( " If the nickels were dimes, the dimes were quarters, and the quarters were nickels, the total would be $3.75.
\n" ); document.write( ".10n + .25d + .05q = 3.75
\n" ); document.write( ":
\n" ); document.write( "using the matrix feature on your calc,enter
\n" ); document.write( " 1, 1, 1, 25
\n" ); document.write( ".05 .1 .25 2.75
\n" ); document.write( ".1 .25 .05 3.75
\n" ); document.write( "you get: 10 nickels, 10 dimes, 5 quarters
