Nancy’s Pool (Part 2): Nancy has a nice pool in her backyard. Her pool is 15 feet by 30 feet with a depth of about 6 feet, though she’ll only fill it with water to 5 feet 4 inches. One way to provide the pool with chlorine is to give it a weekly “shock treatment” of chlorine. You may use your work from Nancy’s Pool (Part 1) as needed. A – One product says to add 1 bottle of the product every week for every 12,000 gallons in the pool. How many bottles should Nancy use weekly in her pool? Round your answer to two decimal places, if necessary. B – Nancy only keeps the pool usable for her kids’ summer break from school, which is 14 weeks long. The “shock” treatment bottles are sold as 6-packs for $24.97. How many 6-packs will Nancy need to buy to have enough for the summer? How much will this cost?
