With summer approaching, the number of air conditioners sold is expected to be doubled that of stoves and refrigerators combined.
\n" ); document.write( "a = 2(s + r)
\n" ); document.write( "--------------------
\n" ); document.write( "Stoves sell for $200, refrigerators for $300, and air conditioners for $350, and sales are expected to be $76000.
\n" ); document.write( "200s + 300r + 350a = 76000
\n" ); document.write( "--------------------
\n" ); document.write( "If stoves and refrigerators sell in equal numbers,
\n" ); document.write( "s = r
\n" ); document.write( "-------------------
\n" ); document.write( "System:
\n" ); document.write( "s - r + 0 = 0
\n" ); document.write( "2s + 2r - a = 0
\n" ); document.write( "200s + 300r + 350a = 76000
\n" ); document.write( "-------------------------------
\n" ); document.write( "Solve the system by any method you know to get:
\n" ); document.write( "s = 40 (# of stoves to be stocked)
\n" ); document.write( "r = 40 (# of refrigerators to be stocked)
\n" ); document.write( "a = 160 (# of air conditioners to be stocked)
