\n" ); document.write( "--------------------------------
\n" ); document.write( "Equations:
\n" ); document.write( "n = 3p
\n" ); document.write( "q = 2n
\n" ); document.write( "25q + 5n + p = 332 cents
\n" ); document.write( "-----------------
\n" ); document.write( "Rearrange:
\n" ); document.write( "p = 1/3 n
\n" ); document.write( "q = 2n
\n" ); document.write( "25q + 5n + p = 332
\n" ); document.write( "-------------------------
\n" ); document.write( "Substitute and solve for \"n\":
\n" ); document.write( "25(2n) + 5n + (1/3)n = 332
\n" ); document.write( "[55 1/3]n = 332
\n" ); document.write( "(166/3)n = 332
\n" ); document.write( "166n = 996
\n" ); document.write( "n = 6 (# of nickels)
\n" ); document.write( "p = (1/3)n = 2 (# of pennies)
\n" ); document.write( "q = 2n = 12 (# of quarters)
