What types of materials should be paid to the contractor upon delivery, even before they are assembled into the completed work?
A machine cost $450,000 to purchase. Fuel, oil, grease, and minor maintenance areestimated to cost $55.00 per operating hour. A set of tires cost $18,000 to replace, and theirestimated life is 3,100 use hours. A $27,000 major repair will probably be required after6,200 hr of use. The machine is expected to last for 9,300 hr, after which it will be sold at aprice (salvage value) equal to 20% of the original purchase price. A final set of new tireswill not be purchased before the sale. How much should the owner of the machine chargeper hour of use, if it is expected that the machine will operate 3,100 hr per year? Thecompany’s cost of capital (interest) rate is 8.3%.

2 CarpetPlus sells and installs floor covering for commercial buildings. Brad Sweeney. CarpetPlus account executive, was just awarded the contract for five jobs. Brad must now assign a CarpetPlus installation crew to each of the five jobs. Because the commission Brad will earn depends on the profit CarpetPlus makes, Brad would like to determine an assignment that will minimize total installation costs. Currently, five installation crews are available for assignment, Fach crew is identified by a color code, which aids in tracking ofjob progress on a large white board. The following table shows the costs (in hundreds of dollars) for each crew to complete each of the five jobs: Jeb 2 Red White Blue 38 45 37 37 47 32 40 38 34 Crew Green Bronn Use the Hungarian method to solve the problem
