Sonja has some nickels and dimes. If she has 30 coins worth a total value of $2.00, how many of each type of coin does she have?
\n" ); document.write( ":
\n" ); document.write( "Let n = no. of nickels; Let d = no. of dimes
\n" ); document.write( ":
\n" ); document.write( "Write the number of coins equation:
\n" ); document.write( "n + d = 30
\n" ); document.write( "Which can be also written:
\n" ); document.write( "n = (30 - d)
\n" ); document.write( ":
\n" ); document.write( "Write the value equation:
\n" ); document.write( ".05n + .10d = 2.00
\n" ); document.write( ":
\n" ); document.write( "Substitute (30-d) for n in the above equation, find d:
\n" ); document.write( ".05(30-d) + .10d = 2.00
\n" ); document.write( "1.5 -.05d + .10d = 2
\n" ); document.write( ".05d - .10d = 2 - 1.5
\n" ); document.write( ".05d = .50
\n" ); document.write( "d = .50/.05
\n" ); document.write( "d = 10 dimes:
\n" ); document.write( ":
\n" ); document.write( "You can find the number of nickels using the no. of coins equation:
\n" ); document.write( ":
\n" ); document.write( "Check your solutions in the value equation. \n" ); document.write( "
\n" );
