$9-68.$ Tume$-$Based ABC: Tume Equations

$(\mathrm{.}9)$

Page $399$

Refer to Exercise $9\mathrm{.}52.$ Until now, KDS used a commercial vendor to ship orders. The manager of Distribution believes the system described in $6$ Evercise $9-52$ is too simple in two ways. First, if a retailer is ordering from KDS for the first time, Distribution has to take time to verify the Retailer details $($shipping address, credit, and so on$).$ The manager estimates this additional time to total $30$ minutes. In addition, some orders are quite complex. This happens when a retailer orders many different items in one order. The manager estimates that a complex order takes an additional $20$ minutes to pick, on average.

Required

a$.$ Write out the time equation for taking an order.

$b$ Write out the time equation for picking an order.

c$.$ Using the data fromity Exercise $9\mathrm{.}52$ and the additional data here, compute the cost of filling a complex order from a new retailer. Assume that all of the items in the order are in stock and that the retailer will not pick the order up at the KDS loading dock.
