Let number of nickels be \"n\"
\n" ); document.write( "Let number of dimes be \"d\"
\n" ); document.write( "QUANTITY EQUATION:
\n" ); document.write( " n + d = 52
\n" ); document.write( "Value of nickels = 5n cents
\n" ); document.write( "Value of dimes = 10q cents
\n" ); document.write( "VALUE EQUATION:
\n" ); document.write( " 5n + 10d = 450 cents
\n" ); document.write( "Solve by substitution as follows:
\n" ); document.write( " n = 52-d
\n" ); document.write( "5(52-d)+ 10d = 450
\n" ); document.write( "260 - 5d +10d = 450
\n" ); document.write( " 5d = 190
\n" ); document.write( " d = 38 (number of dimes)
\n" ); document.write( " n = 14 (number of nickels) \r
