(This is the same problem as the previous one. The question is different.)

The University Bookstore at a private university buys pencils from a wholesaler. The wholesaler offers discounts for large orders according to the following price schedule:

Quantity Range	Price per Unit
1-199	$3.90
200-599	$3.40
600+	$3.25

The bookstore expects an annual demand of 2,600 units. It costs $12 to place an order, and the annual cost of holding a unit in stock is 20% of the unit's price.

What will be the total purchasing cost if they order 150 pencils every time they contact the supplier? (round to two decimal places.)
