Ron has 16 coins with a total value of $2.20. The coins are nickels and quarters. How many of each coin does he have?
\n" ); document.write( "-------------
\n" ); document.write( "Quantity Eq:: n + q = 16 coins
\n" ); document.write( "Value Eq:::: 5n+25q = 220 cents
\n" ); document.write( "------------------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "n + q = 16
\n" ); document.write( "n + 5q = 44
\n" ); document.write( "----
\n" ); document.write( "Subtract and solve for \"q\"::
\n" ); document.write( "4q = 28
\n" ); document.write( "q = 7 (# of quarters)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"n\"::
\n" ); document.write( "n = 16-7 = 9 (# of nickels)
\n" ); document.write( "----------
