Bike Zone, a bicycle retailer, offers a discounted accessory bundle when customers purchase a bike. The accessory bundle includes a water bottle holder, bike lock, and front light. The stand-alone prices for these accessories are $15, $20, and $30, respectively. Bike Zone estimates that 60% of bike buyers take advantage of this accessory bundle offer.
