Consider the planning of undergraduate education for all three kids that a young couple plans to have. The costs depend on the number of kids that go to college (X) and the number of years each takes to complete the degree (Y). We denote the cost by C. Thus C= g(X, Y)

Suppose the joint probability mass function of X, and Y for the planning couple is as follows:

x/y 3 4 5
1 0.05 0.05 0
2 0.07 0.3 0.03
3 0 0.4 0.1

Suppose the cost function is (in tens of thousands)
C = g(X, Y) = 10X + 20Y

What is the expected cost C?

Xie company identified the following activities, costs, and activity drivers for 2017. the company manufactures two types of go-karts: deluxe and basic. activity expected costs expected activity handling materials $ 625,000 100,000 parts inspecting product 900,000 1,500 batches processing purchase orders 105,000 700 orders paying suppliers 175,000 500 invoices insuring the factory 300,000 40,000 square feet designing packaging 75,000 2 models required: 1. compute a single plantwide overhead rate, assuming that the company assigns overhead based on 125,000 budgeted direct labor hours. 2. in january 2017, the deluxe model required 2,500 direct labor hours and the basic model required 6,000 direct labor hours. assign overhead costs to each model using the single plantwide overhead rate.

Henry crouch's law office has traditionally ordered ink refills 55 units at a time. the firm estimates that carrying cost is 35% of the $11 unit cost and that annual demand is about 240 units per year. the assumptions of the basic eoq model are thought to apply. for what value of ordering cost would its action be optimal? a) for what value of ordering cost would its action be optimal?
