The Beef Taco Dilemma

This is a problem that I wrote for my statistics class.  The objectives for this problem are as follows:

1.  Compute percentages.
2.  Compute the arithmetic mean.
3.  Critically think about whether or not Joe had enough tacos to meet the ‘average’ demand.


What I found was some students had a hard time computing the percentages and some also had a hard time keeping straight how many beef and how many chicken tacos Joe ordered on each day.
