Kitchen Aid (KA) manufactures cordless mixers for residential use. KA sells to retailers (such as William Sonoma, Sur La Table, etc.) who sell the mixers to individual consumers. One of KAs retail customers is Jones Kitchenware (JK). On January 1, KA sells to and receives payment from JK for 100 cordless mixers with a one-year warranty for $50 each. The mixers are delivered by KA to JK upon receipt of payment and the warranty is initiated at that time. This warranty provides for a replacement of the mixer if the mixer fails to function. KA also provides the standalone selling price of its mixers with no warranty at $40 per unit. The cost to manufacture each mixer is $32.

KA also provides its retail customers with sales incentives in the form of volume discounts on purchases of mixers with warranties paid at the end of an annual period. The agreement between KA and JK provides for the following volume discounts. Additionally, the probability of purchases for each volume level as estimated by KA is provided based on historical experience and forecasted sales.

Number of mixers purchased	Discount	Probability
Less than 1,000	0.00%	35.00%
1,000 through 1,999	3.75%	40.00%
2,000 or more	10.00%	25.00%

The discounts are retroactive, meaning if JK purchases a total of 2,000 mixers during the year, a discount of 10% will be applied to all 2,000 mixers at year-end.
