he cost of producing x bags of pretzels is modelled by C(x)=0.5x^2 + x + 2 where x=# of bags per hundred. State the function that represents the average cost.
Do you just have to factor it?

Average cost is C(x)/(100 x)
(since the number of bags is seems to be 100x). In your statement of the problem, if is unclear if x is the number of bags or the number of hundreds of bags.
