A major issue of contention at many colleges concerns the cost of meals that is rebated when a student does not sign up for the meal plan. The administration usually says that it should rebate only the marginal cost of the food alone, which it calculated at, say, $1.25 per meal. Students say that the marginal cost should include more costs, such as the saved space from fewer students using the facilities and the reduced labor expenses on food preparation. This can raise the marginal cost to $6.00.

• Who is correct, the administration or the students?
• How might your answer differ if this argument were being conducted in the planning stage before the dining hall is built
• If you accept the $1.25 figure of a person not eating, how could you justify using a higher figure of about $6.00 for the cost of feeding a guest at the dining hall, as many schools do?

Northwood Company manufactures basketballs. The company has a ball that sells for $32. At present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus, variable expenses are high, totaling $22 per ball, of which 69% is direct labor cost. Last year, the company sold 30,000 of these balls, with the following results: Sales (30,000 balls) $ 960,000

Variable expenses 660,500

Contribution margin 300,000

Fixed expenses 210,000

Net operating income $ 90,000

Required: 5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 31.25%, but it would cause fixed expenses per year to DOUBLE. If the new plant is built, what would be the company’s new break-even point in balls? (Do not round intermediate calculations.) 6. Refer to the data in (5) above. a. If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $90,000, as last year? (Do not round intermediate calculations.) b-1. Assume the new plant is built and that next year the company manufactures and sells 30,000 balls (the same number as sold last year). Prepare a contribution format income statement (Do not round your intermediate calculations.) b-2. Compute the degree of operating leverage. (Do not round intermediate calculations and round your final answer to 2 decimal places.)

A model of a plane is built to a scale of 1/14 and is tested in a wind tunnel.

If the plane is designed to travel at 800 km/h at an altitude of 5 km, determine the required density of the air in the wind tunnel so that the Reynolds and Mach numbers are the same. Assume the temperature is the same in both cases and the speed of sound in air at this temperature is 340 m/s. ρp = 0.7364 kg/m3 at an altitude of 5 km.

Samuelson and Messenger (SAM) began 2021 with 320 units of its one product. These units were purchased near the end of 2020 for $24 each. During the month of January, 160 units were purchased on January 8 for $27 each and another 320 units were purchased on January 19 for $29 each. Sales of 215 units and 210 units were made on January 10 and January 25, respectively. There were 375 units on hand at the end of the month. SAM uses a periodic inventory system. 1. Calculate ending inventory and cost of goods sold for January using FIFO. 2. Calculate ending inventory and cost of goods sold for January using average cost.

1. Calculate ending inventory and cost of goods sold for January using FIFO.
2. Calculate ending inventory and cost of goods sold for January using average cost.

A graph G = (V, E) is a near-tree if it is connected and has at most n+ 8 edges, where n = |V |. Give an algorithm with running time O(n) that takes a near-tree G with costs on its edges, and returns a minimum spanning tree of G. Assume all the edge costs are distinct.

okay so I took this quiz and these are the answers I put. there are 13 questions but I am not sure what I am getting wrong. all I know is I got 9 out of 13 right.

A new publicly financed bridge is expected to reduce the cost of auto travel between two areas by Php1 per trip. This cost reduction to motorists consists of a reduction in travel time, auto depreciation and petrol expenses totaling Php1.50 per trip, less the Php0.50 bridge toll which the government will collect. Before the bridge was built there were 1 million trips per year between the two areas. Once the bridge is in operation, it is estimated that there will be 1.5 million trips per year between the two areas. In terms of areas under the demand curve, what is the annual benefit of the bridge:

To motorists?

To the government?

What other referent group benefits would need to be considered in a social benefit/cost analysis?
