Hult Games buys electronic components for manufacturing from two suppliers, Milan Components and Dundee Parts. If the components are delivered late, the shipment to the customer is delayed. Delayed shipments lead to contractual penalties that call for Hult to reimburse a portion of the purchase price to the customer.

During the past quarter, the purchasing and delivery data for the two suppliers showed the following.

	Milan			Dundee			Total
Total purchases (cartons)		147,000			63,000			210,000
Average purchase price (per carton)	$	10.00		$	12		$	10.60
Number of deliveries		80			20			100
Percentage of late deliveries		25	%		10	%		22	%

The Accounting Department recorded $861,000 as the cost of late deliveries to customers.

Assume that the average quality, measured by the percentage of late deliveries, and prices from the two companies will continue as in the past.

Required:

What percentage of late deliveries by Milan would make Hult indifferent between buying from Milan Components and Dundee Parts?
