a. Formulate this problem, what is the optimal leasing plan?

b. Formulate the dual.

c. If DMA must make do with one less worker to operate its fleet, should it be a mechanic, pilot or

flight attendant?

d. Excluding certain fixed costs (including pilot costs), each seat of fleet capacity gives DMA a net

yearly profit of $25,000. If DMA plans to pay its pilots $110,000 per year, including benefits, should

it hire an additional pilot?

e. DMA is considering redesigning the interior of the B77 to increase its seat capacity beyond 70.

What is the maximum seating capacity for which the leasing plan found in part (a) remains optimal?

f. Suppose DMA could squeeze one more row of three seats into each of the two types of aircrafts,

increasing each planes seating capacity by 3. Given no other changes, would the optimal leasing decision

change? Would you consider any other more practical changes before trying to implement this one?

DMA plans to have 11 mechanics, 15 pilots, and 21 flight attendants available daily.
