The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer, independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000 wafers. Assume a 20% annual interest rate for holding cost calculations. a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the optimal order quantity? b. If the replenishment lead time for wafers…

Need help filling out the table with the data I have (1st row is fine but show work please)

Help please I'm stuck on these two problems.

(b) A special sprinkler system is comprised of three identical humidity sensors, a digital controller, and a pump, of which the reliability is 0.916, 0.965, and 0.983 respectively. The system configuration is shown in the figure below. Sensor Controller Pump Reliability block diagram of a sprinkler system. (b) Calculate the reliability of the sprinkler system. (c) Discuss the importance of safety in an engineering maintenance.
