6. When you find income elasticity of demand, you can determine whether the goods are normal or inferior based on whether your answer is a positive or negative number. Explain. Include definitions of inferior and normal goods in your explanation.

The winston company estimates that the factory overhead for the following year will be $1,250,000. the company has decided that the basis for applying factory overhead should be machine hours, which is estimated to be 50,000 hours. the total machine hours for the year were 54,300. the actual factory overhead for the year were $1,375,000. determine the over- or underapplied amount for the year.

Southeastern bell stocks a certain switch connector at its central warehouse for supplying field service offices. the yearly demand for these connectors is 15,000 units. southeastern estimates its annual holding cost for this item to be $25 per unit. the cost to place and process an order from the supplier is $75. the company operates 300 days per year, and the lead time to receive an order from the supplier is 2 working days.a) find the economic order quantity.b) find the annual holding costs.c) find the annual ordering costs.d) what is the reorder point?

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
