Reative Computing sells a tablet computer called the Protab. The $920 sales price of a Protab Package includes the following: One Protab computer. A 6-month limited warranty. This warranty guarantees that Creative will cover any costs that arise due to repairs or replacements associated with defective products for up to six months. A coupon to purchase a Creative Probook e-book reader for $400, a price that represents a 50% discount from the regular Probook price of $800. It is expected that 25% of the discount coupons will be utilized. A coupon to purchase a one-year extended warranty for $45. Customers can buy the extended warranty for $45 at other times as well. Creative estimates that 30% of customers will purchase an extended warranty. Creative does not sell the Protab without the limited warranty, option to purchase a Probook, and the option to purchase an extended warranty, but estimates that if it did so, a Protab alone would sell for $900.
