\ x1 = number of long-range planes
\ x2 = number of medium-range planes
\ x3 = number of short-range planes

maximize 2100 x1 + 1500 x2 + 1150 x3


subject to

33500 x1 + 25000 x2 + 17500 x3 <= 750000       \ cost limit

      x1 +       x2 +       x3 <=     30       \ pilot limit

    5 x1 +     4 x2 +     3 x3 <=    120       \ maintenance limit

general

x1 x2 x3
