Recalling that the setup cost for the single print run is $5,000, the cost of producing 1,200,000 books at $1 each is $1,200,00, the total cost for the year would be given by, C = (Setup Costs) + (Production Costs) + (Storage Costs) = $5000 + $1,200,000 + $72,000 = $1,277,000 1. You have an idea. To cut down on storage costs you will print the book in two print runs of 600,000 each, as shown in the figure below. A) What are the setup costs for two print runs? B) What are the production costs? C) What are the storage costs? D) What is the total cost for the year? 2. It appears to you that increasing the number of print runs reduces total costs for the year. Motivated by this idea, you decide to divide the 1,200,000 books into a twelve-monthly production runs of 100,000 books each. A) Create a graph similar to the one in Problem #1 of this exam. Use graph paper and include the graph for your work in this part (You can glue the graph to your exam paper if necessary). Label both…
Some students want to start a business that cleans and polishes cars. It takes 2.5 hours of labor and costs $1.5 in supplies to clean a car. It takes 1.5 hours of labor and costs $3 in supplies to polish a car. The students can work a total of 150 hours in one week. They also decide that they want to spend no more than $120 per week on supplies. The students expect to make a profit of $6.75 for each car that they clean and a profit of $9.50 for each car that they polish. The objective function is: * Maximize Z=7.75X1+8.5X2 Maximize Z=6.75 X1+9.5X2 Maximize Z=2.5X1+1.5X2 Maximize Z=9.5 X1+6.75X2
