Consider boeing (a producer of jet aircraft), general mills (a producer of breakfast cereals), and wacky jack's (which claims to be the largest u. s. provider of singing telegrams). for which of these firms is the long run the longest period of time? for which is the long run the shortest? explain.

The long run is longest for Boeing and shortest for Wacky Jack's.

Explanation:

Boeing is an aircraft manufacturer, General Mills produces cereals and Wacky Jack's is the largest provider of singing telegrams. Out of these three, the longest long run will be for Boeing. This is because making aircraft needs lots of inputs, big machine, and equipment and it is a large scale work.  

The shortest long run will be for Wacky Jack's. This because this firm provides singing telegrams. It requires only primary labor to make singing telegrams.
