Question

Need ASAP Alice runs a Delicatessen. She makes her tuna sandwiches for the lunch rush in advance. Each can of tuna she buys make 24 sandwiches, and each takes about four minutes from start to finish if she spends the 10 minutes prior laying out all of her food components and ingredients. After making 4 sandwiches she needs to stack them in a cooler which takes about 1 minute. How long does it take Alice to finish making the sandwiches? If she comes 2 hours before the lunch rush what would be her utilization rate? If you want to improve the utilization rate, where in the sandwich preparation process would you reduce the time?
