This week a carpenter made some three-legged stools and some four-legged chairs. The total number of stools and chairs was 30, and the carpenter used 103 legs in all. How many chairs did the carpenter make?
\n" ); document.write( "--------
\n" ); document.write( "# of stools EQ: t + f = 30
\n" ); document.write( "# of legs EQ:: 3t +4f = 103
\n" ); document.write( "-------------------
\n" ); document.write( "Multiply thru stools EQ be 3 to get:
\n" ); document.write( "3t + 3f = 3*30
\n" ); document.write( "3t + 4f = 103
\n" ); document.write( "----
\n" ); document.write( "subtract and solve for \"f\":
\n" ); document.write( "f = 13 (# of four-legged stools)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"t\":
\n" ); document.write( "t + f = 30
\n" ); document.write( "t + 13 = 30
\n" ); document.write( "t = 17 (# of 3-legged stools)
