When three pumps A,B, and C are running they can pump 3600 gal per hour.
\n" ); document.write( " When only A & B are running 2200 gal per hr can be pumped.
\n" ); document.write( "When only A and C are running 2400 gal per hour can be pumped.
\n" ); document.write( "What is the pumping capacity of each :
\n" ); document.write( ":
\n" ); document.write( "We can solve this easily with elimination
\n" ); document.write( "A + B + C = 3600
\n" ); document.write( "A + B + 0 = 2200
\n" ); document.write( "--------------------Subtraction eliminates A and B, find C
\n" ); document.write( "C = 1400 gal/hr
\n" ); document.write( "and
\n" ); document.write( "A + B + C = 3600
\n" ); document.write( "A + 0 + C = 2400
\n" ); document.write( "--------------------Subtraction eliminates A and B, find C
\n" ); document.write( "B = 1200 gal/h
\n" ); document.write( ":
\n" ); document.write( "I'll let you find A
\n" ); document.write( " \n" ); document.write( "
