Requirement $2.$ Short Sand is considering introducing a new product, Y$28.$ The company expects it will receive $25$ orders of Y$28$ in the coming year. Each order of Y$28$ will take $20$ hours of machine time. Assuming the demand for Z$39$ will not be affected by the introduction of Y$28,$ calculate $($a$)$ the average waiting time for an order received and $($b$)$ the average manufacturing cycle time per orde for each product if Short Sand introduces Y$28.($Abbreviations used: Capacity $=$ Annual machine capacity, Orders Z$39=$ Annual average number of orders of Z$39,$ Orders Y$28=$ Annual average number of orders of Y$28,$ Mfg time Z$39=$ Manufacturing time per order of Z$39,$ Mfg time Y$28=$ Manufacturing time per order of Y$28,$ SP Z$39=$ Selling price per order of Z$39,$ SP Y$28=$ Selling price per order of Y$28,$ VC Z$39=$ Variable cost per order of Z$39,$ VC Y$28=$ Variable cost per order of Y$28.)$

$($a$)$ Calculate the average waiting time for an order received. Begin by selecting the formula to calculate the average waiting time for an order received. $=$ Average wait time

Enter the amounts into the formula now. $($Enter the amounts in the same order as shown in the formula.$)$

$($b$)$ Calculate the average manufacturing cycle time per order for each product if Short Sand introduces Y$28.$

The average manufacturing cycle time per order for Z$39$ if Short Sand introduces Y$28$ is $$ hours.
