A warehouse manager must decide on the number of forklifts to make a proposal for a new facility to minimize the total cost of loading, driver and truck. The manager knows that the total cost of drivers and trucks is $ 300 per day, and the cost of lifting and labor is $ 1,100 per day. A. How many lifts would be needed if a truck would arrive at a rate of 3 per day and each forklift could handle 5 lifts per day, assuming both were poisson-distributed? B. An employee suggested buying additional equipment that would increase the loading speed to six trucks a day. To get this equipment, they will have to pay an additional $ 100 per day for each lift. Should managers invest in this new tool?
