(a) given the information, calculate the following :

1. the variable manufacturing cost per pie made
2. the total variable cost per pie sold
3. the full manufacturing cost per pie made
4. the full cost per pie sold
5. the minimum price at which a pie could be sold to cover its marginal cost
6. the minimum price at which a pie could be sold to cover its full cost.

(b) assuming no change in sales volume, calculate the price at which pies must be sold to ensure an operating profit of $2,250,000.
