Specific instructions for Dr. Taylor's section
## Calculating Costs
Price calculations should be based on the following rules:
### Vegetables
Vegetables should be priced on a per kilogram basis.
* $20.00 per Kg for sea vegetables
* $2.00 per Kg for podded vegetables
* $1.50 per Kg for stem vegetables
* $0.30 per Kg for root vegetables
* $1.00 per Kg for all other vegetables
### Fruit
Aggregate fruits are priced at $2.30 per kilogram. All other fruits are
priced by quantity.
* $0.50 for each stone fruit
* $0.80 for each fleshy fruit
Any other fruit should be given a random per-fruit price between 10 cents
and $2.
### Milk
Skim, 1%, 2%, and whole milk should have a price of $2.50 a gallon. The price of
half and half is double that of skim milk, and the price of cream is triple
the price of skim milk.
### Soft Drinks
The base price for soft drinks is 8 cents for each fluid ounce. The
following two scaling factors should be multiplied by the base price:
1. Container size factor: $ \frac{12N}{V} $
2. Quantity factor: $ 0.99^{N} $
Where $N$ is the number of containers and $V$ is the total volume.
The price should be rounded to the nearest ten cents.
