My piggy bank has 28 coins in it that are only nickels, dimes, and quarters. I have $3.25 total.
\n" ); document.write( "The number of quarters is one less than the number of nickels.
\n" ); document.write( "How many of each coin do I have?
\n" ); document.write( "----------------------
\n" ); document.write( "n + d + q = 28
\n" ); document.write( "5n + 10d + 25q = 325 ---> n + 2d + 5q = 65
\n" ); document.write( "q = n-1
\n" ); document.write( "-----
\n" ); document.write( "Sub for q
\n" ); document.write( "n + d + n-1 = 28

\n" ); document.write( "-----
\n" ); document.write( "n + 2d + 5q = 65
\n" ); document.write( "n + 2d + 5(n-1) = 65
\n" ); document.write( "6n + 2d = 70 ---> 3n + d = 35
\n" ); document.write( "==============
\n" ); document.write( "3n + d = 35
