An automotive parts shop rebuilds carburetors, fuel pumps, and alternators. The numbers of hours to rebuild and then inspect and pack each part are shown in the following table, together with the number of hours of skilled labor available for each task. If the profit is $30 for each carburetor, $35 for each fuel pump, and $25 for each alternator, how many of each should the shop rebuild to obtain the greatest possible profit?

(hours)        Rebulding       Inspecting & packing
carborator      5                          1
fuel pump       4                         1
alternator       3                         0.5
labor available    200                   45

5     1      1    0     0    30
4      1      0    1    0    35
