Jim manages his cash reserves using the order-up-to model: each morning he places an order for cash with the bank and the armored vehicle arrives 2 days later with the money. It is company's policy to pay all workers on the same day, but in rare cases when the company runs out of cash it pays workers as soon as possible while increasing their paycheck by 1% for each day of delay. For each dollar carried the company incurs 15% cost annually, which includes cost of capital and insurance.

(b) Suppose Jim is interested in ensuring that the company immediately satisfies all employee salary requirements with a 95% probability. What is the corresponding order-up-to level?

(c) To reduce lines and move payroll closer to workers, Jim considers opening another payroll office. Exactly half of the workers will receive payments at one office and the other half will receive payments at the other office. Jim plans to divide evenly the total safety stock that it keeps now, putting 50% of it in each of the two payroll offices.
