If a jar contains 21 coins, all of which are either nickles or dimes . And the total value is $1.75 , how many coins of each are in the jar?
\n" ); document.write( "-------
\n" ); document.write( "Quantity:: n + d = 21 coins
\n" ); document.write( "Value:::: 5n + 10d = 175
\n" ); document.write( "----------------------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "n + d = 21
\n" ); document.write( "n + 2d = 87.5
\n" ); document.write( "------------------------
\n" ); document.write( "Subtract and solve for \"d\":
\n" ); document.write( "d = 66.5
\n" ); document.write( "Note:: d must be a positive whole number.
