4. Food Goblin Supermarkets use both cashiers and bag- gers to serve customers at check out. During the first 6 hours of each workday (Monday-Friday), 4 cashiers and 2 baggers serve approximately 20 customers per hour. A cashier and a bagger who require approximately 5 minutes at checkout and 5 minutes at bagging serve each customer. a. Calculate the utilization of both cashiers and baggers. b. Assume that both baggers and cashiers are cross- trained to perform both activities so that they can serve customers independently. Customers are now both checked and their groceries bagged by one indi- vidual. Further, assume that it takes 12 minutes for one individual to both cash out and bag each cus- tomer's groceries. Calculate the utilization of this new group of 6 cross-trained employees. 5. Returning to Problem 4, under both assumption of cashiers and baggers working together (part [a]) and cross-trained working independently (part [b]), how many employees should Food Goblin Supermarket schedule if it requires a 10 percent capacity cushion
