The min/max production of each generator corresponds to the min/max production values
in the table (i.e., Generator 1 produces at least 100 MWh and no more than 400 MWh).
(a) Plot the inverse supply function for this system.
(b) If the demand is completely inelastic and equal to 1600 MWh
į. compute the electricity price.
ii. calculate the gross consumer surplus, consumer surplus, the producers revenue, the
producers profit, and the global welfare.
iii. determine the production level, cost, revenue, and profit for each generator.
