Word Problem: The senior class is selling greeting cards.
\n" ); document.write( "Birthday Cards sell for $5.00 a box.
\n" ); document.write( "Thank You cards sell for $7.00 a box.
\n" ); document.write( "You sold 4 more boxes of birthday cards than thank you cards.
\n" ); document.write( "your total sales was $152.00.
\n" ); document.write( "How many Boxes of each kind did you sell?
\n" ); document.write( "---------------------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq.:: b = t+4
\n" ); document.write( "Value Eq.:::: 5b + 7t = 152
\n" ); document.write( "-------
\n" ); document.write( "Rearrange for Matrix:
\n" ); document.write( "b - t = 4
\n" ); document.write( "5b +7t = 152
\n" ); document.write( "--------------------
\n" ); document.write( "Using a Matrix Method I get:
\n" ); document.write( "b = 15 (# of birthday card boxes sold)
\n" ); document.write( "t = 11 (# of thankyou card boxes sold)
\n" ); document.write( "============================================
