Assume that General Dynamics, which manufactures high-technology instruments for spacecraft, is considering the sale of a navigational unit to a government agency in India that wishes to launch its own communications satellite. The government agency plans to purchase 8 units, although it would also consider buying 16 units. General Dynamics has started a chart relating labor time required to units produced. Unit Produced (X) Time Required toProduce the Xth Unit 1 10,000 hours 2 8,000 hours 4 6,400 hours 8 ? 16 ? Required: a. Compute the labor time required to produce 8 and 16 units.b. Assume that labor time costs $125 per hour. Compare the cost of producing the 1st unit to the cost of producing the 16th unit. What is the percentage of the cost of the 16th unit to the cost of the 1st unit?

Please do whole question with all parts done correctly Farmer John sells fruit and vegetables at a farmer’s market in the middle of a city. He is bringing tomatoes to the city for this weekend’s farmer’s market. The tomatoes are very ripe and, therefore, he will need to sell the tomatoes at the farmer’s market and then have to discard any that were not sold. However, there is a cost to the farmer to bring tomatoes into the city for the farmer’s market. In particular, it costs the farmer $1.75 per case of tomatoes to prepare them and bring them to the market. Farmer John can sell each case for $4.5. Farmer John estimates that he will be able to sell 12, 13, 14, or 15 cases of tomatoes at the farmer’s market. Based on historical sales, he believes that the probabilities of being able to sell 12, 13, 14, and 15 cases are 0.1, 0.3, 0.4, and 0.2, respectively.

Data Products, Inc., packages and distributes a variety ofpersonal computer-related products. A time study hasbeen conducted for a job packaging 3.5-inch personalcomputer diskettes for shipment to customers. The jobrequires a packager to place 20 diskettes in a rectangularplastic bag, close the bag with a twist tie, and place thefilled bag into a bin, which is replaced by another workerwhen it is filled. The job can be broken into four basic elements. The elemental times (in minutes) were ob-tained from the time study for 10 job cycles shown in the following table. a. Using an allowance factor of 16%, determine the stan-dard time for this job. b. Determine the number of cycles for this time studysuch that the company would be 95% confident that theaverage time from the time study is within 4% of thetrue average cycle time.
b) A company receives parts from suppliers to be used in its manufacturing departments. The quality control department must perform two operations when shipments are received: Operation A – draw a random sample, package, and deliver to testing; and Operation B – test the materials and issue a disposition report.

5. During the construction of a house, six joists of 24 ft each must be trimmed to the correct length of 23 ft. The operations for cutting a joist involve the following sequence: Operation 1. Place joist on saw horses 2. Measure correct length (23 ft) 3. Mark cutting line for circular saw 4. Trim joist to correct length 5. Stack trimmed joist in a designated area Time (seconds) 15 5 5 20 20 Three persons are involved: Two loaders must work simultaneously on operations 1,2, and 5, and one cutter handles operations 3 and 4. There are two pairs of saw horses on which untrimmed joists are placed in preparation for cutting, and each pair can hold up to three side-by-side joists. Suggest a good schedule for trimming the six joists.
