When three pumps, A, B, and C, are running together, they can pump 3500 gal per hour. When only A and B are running, 2100 gal per hour can be pumped. When only A and C are running, 2400 gal per hour can be pumped. What is the pumping capacity of each pump?
--------------
A + B + C = 3500
A + B = 2100
A + C = 2400
---------------
A + B + C = 3500
A + B = 2100
---------------- Subtract
C = 1400
A = 1000
B = 1100
