TRY'nSAVE, a grocery store, is considering offering click and collect service in their store. The company expects that sales from the new service will be $160,000 per year. While many of the click and collect sales will be to new customers, TRY'nSAVE estimates that 65% of the click and collect sales come from in-store customers. Note: Select the correct answer from the dropdown list in part a and part b. a. The level of incremental sales associated with introducing the click and collect service is $56,000 b. Suppose that if TRY'nSAVE fails to introduce the click and collect service, 60% of the customers switched from in-store purchase to click and collect service would start using a competitor's click and collect service. The level of incremental sales, in this case, is closest to $118,400
