OC userin Computer ScienceΒ·10 Dec 201729. Recall that some IP addresses are reserved for private use (e.g., in a home, small business, or portions of a larger network). An example are addresses 10.0.0.0 to 10.255.255.255, used for private networks. All IP packets have a source IP address and a destination IP address. Then a Network Address Translation (NAT) is used so that a) Packets passing from private network to public network have their destination addresses modified. b) Typically packets passing from the private network to the public network have their source addresses modified while packets passing from the public network back to the private network have their destination addresses modified. x c) Packets passing from public network to private network have their source addresses modified. d) Typically packets exchanged between private and public networks have both their source and destination addresses unchanged. e) All of the above

Suppose a problem develops with car-seat heaters - they malfunction and occasionally cause serious burns. As a result, demand decreases by 100 heaters at each price. Simultaneously, the cost of production rises, and supply decreases by 100 heaters at each price. The new equilibrium price is $ 66 and the new equilibrium quantity is 300 heaters per month.

OC userin AccountingΒ·10 Dec 2017EXERCISE 3-14 Computing Predetermined Overhead Rates and Job Costs [LO3-1, L03-2, L03-3, LO3-7] Moody Corporation uses a job-order costing system with a plantwide overhead rate based on machine-hours. At the beginning of the year, the company made the following estimates: Machine-hours required to support estimated production ...... Fixed manufacturing overhead cost .... Variable manufacturing overhead cost per machine-hour ....... 100,000 $650,000 $3.00 Required: 1. Compute the predetermined overhead rate. 2. During the year, Job 400 was started and completed. The following information was available with respect to this job: $450 Direct materials requisitioned ..... Direct labor cost ... Machine-hours used ...... $210 40 Compute the total manufacturing cost assigned to Job 400. During the year, the company worked a total of 146,000 machine-hours on all jobs and incurred actual manufacturing overhead costs of $1,350,000. What is the amount of underap- plied or overapplied overhead for the year? If this amount were closed out entirely to Cost of Goods Sold would the journal entry increase or decrease net operating income?
