Assuming the distribution does not change, the lab should budget $656.50 for next year's rat orders.

We calculate expected price as follows:

Expected Price = (10*0.4) + (12.5 * 0.15) + (15*0.45)

Expected Price = $ 12.625 (4+1.875+6.75)

Since the expected price is for a week's shipment of rats,

Annual Expense = Expected Price * No. of weeks per year

Annual Expense = $ 12.625 * 52

Annual Expense = $656.5
