Thomas Built Buses (TBB) manufacturers yellow school buses at its facility in High Point, NC. TBB orders its windshields from a specialty vehicle glass supplier. Weekly requirements for the windshields are normally distributed with a mean of 196 units/week and standard deviation of 94 units/week. Lately, the supplier has been unreliable with its deliveries. TBB estimates the lead time is normally distributed with mean 5 weeks and standard deviation 3 weeks. TBB orders the windshields at a unit cost of $2773. The annual cost of carrying inventory at the plant is 19% of the purchase cost per unit per year. TBB reviews its windshield inventory continuously. Assume 52 weeks/year, 7 days/week, and 364 days/year. Compute the annual holding cost of the safety stock (in \$) needed to maintain a service level of 92%. - Carry calculations to at least 3 decimal places. - Round your answer to the nearest tenth of a dollar (one decimal place).
