1.	Two generators have cost functions F1 and F2. Their incremental-cost characteristics are\(\frac{{d{F_1}}}{{d{P_1}}} = 40 + 0.2{P_1}\)\(\frac{{d{F_2}}}{{d{P_2}}} = 32 + 0.4{P_2}\)They need to deliver a combined load of 260 MW. Ignoring network losses, for economic operation, the generations P1 and P2 (in MW) are
A.	P1 = 140, P2 = 120
B.	P1 = 120, P2 = 140
C.	P1 = P2 = 130
D.	P1 = 160, P2 = 100
