\n" ); document.write( "one small pizza, a liter of soda, and three salads cost $15;
\n" ); document.write( "and three small pizzas and a liter of soda cost $16.
\n" ); document.write( "--------------------
\n" ); document.write( "What is the cost of one small pizza?
\n" ); document.write( "---------------
\n" ); document.write( "Equations:
\n" ); document.write( "2p + d + s = 14
\n" ); document.write( "p + d +3s = 15
\n" ); document.write( "3p + d + 0 = 16
\n" ); document.write( "=====================
\n" ); document.write( "Use any method you know to solve to get:
\n" ); document.write( "p = $5 (price of one pizza)
\n" ); document.write( "d = $1 (price of one soda)
\n" ); document.write( "s = $3 (price of one salad)
