14.3. We offer a special breakfast cereal bowl for $0.25 plus 10 proofs-of-purchase (a.k.a. boxtops). Cost of bowl = $0.75. We estimate 60% of boxtops will be redeemed. Offer begins 6/1/2kA; we acquire 20k bowls to satisfy expected demand. Sales by 6/30/2kA = 300k cereal boxes. Assume 60k boxtops are redeemed by 6/30/2kA; provide entries for June.
