Expert Solution & Answer

Explanation of Solution

Table-1 shows the cash flow of two different projects.

Table-1

Item	1	2
Initial cost (C)	1,200,000	2,000,000
Annual maintenance cost (AM)	80,000	75,000
Annual benefit (B)	520,000	580,000
Annual disbenefit (DB)	90,000	140,000
Time period (n)	10	20

The interest rate (i) is 8%.

The alternatives are ranked based on the initial cost of the alternate. The first is do nothing, the second is alternate 1, and the third is alternate 2.

The incremental benefit–cost ratio (BC) between the initial alternate, do nothing, and the new alternate 1 can be calculated as follows.

BC=B1−DB1C1(i(1+i)n1(1+i)n1−1)+AM1=520,000−90,0001,200,000(0.08(1+0.08)10(1+0.08)10−1)+80,000=430,0001,200,000(0.08(2.158925)2.158925−1)+80,000=430,0001,200,000(0.1727141.158925)+80,000=430,0001,200,000(0.149029)+80,000=430,000178,834.8+80,000=430,000258,834.8=1.66

The incremental benefit–cost ratio is 1.66. Since the incremental benefit–cost ratio is greater than 1, select the new alternate 1 and eliminate the initial alternate do nothing.

The incremental benefit–cost ratio (BC) between the initial alternate 1 and new alternate 2 can be calculated as follows:

BC=(B2−B1)−(DB2−DB1)(C2(i(1+i)n2(1+i)n2−1)+AM2)−C1(i(1+i)n1(1+i)n1−1)+AM1=(580,000−520,000)−(140,000−90,000)(2,000,000(0.08(1+0.08)20(1+0.08)20−1)+75,000)−(1,200,000(0.08(1+0.08)10(1+0.08)10−1)+80,000)=60,000−50,000(2,000,000(0.08(4.660957)4.660957−1)+75,000)−(1,200,000(0.08(2.158925)2.158925−1)+80,000)=10,000(2,000,000(0.3728773.660957)+75,000)−(1,200,000(0.1727141.158925)+80,000)=10,000(2,000,000(0.101852)+75,000)−(1,200,000(0.149029)+80,000)=10,000(203,704+75,000)−(178,834.8+80,000)=10,0002798,704−258,834.8=10,0002798,704−258,834.8=10,00019,869.2=0.503

Suppose that a paper mill "feeds" a downstream box mill. For the downstream mill, the marginal profitability of producing boxes declines with volume. For example, the first unit of boxes increases earnings by $10, the second by $9, the third by $8, and so on, until the tenth unit increases profit by just $1. The cost the upstream mill incurs for producing enough paper (one "unit" of paper) to make one unit of boxes is $3.50. Assume the two mills operate as separate profit centers, and the paper mill sets the price of paper. It follows that the marginal profitability of boxes represents the highest price that the box division would be willing to pay the paper division for boxes.. Furthermore, assume that fixed costs are $0 for the paper mill. The following table summarizes the quantity, total revenue, and marginal costs from the perspective of the paper mill for selling paper to the box mill at various prices. In the following table, fill in the marginal revenue, total cost, and total…

Planes frequently push back from the gate on time, but then wait 2 feet away from the gate until it is time to queue up for takeoff. This increases fuel consumption and increases the time that passengers must sit in a cramped plane awaiting takeoff. The following table shows the pay schedule for the flight crew. Pay Per diem Holding pay per hour Flight Attendant Captain First Officer $3 $3 $3 $20 $20 $20 Hourly wage (after push back) $38 $184 $50 Per diem pay indicates how much the flight crew earns once it checks into the airport. Holding pay indicates how much the flight crew earns after it loads the plane. Hourly wage indicates how much the flight crew earns after it pushes back from the gate and turns on the beacon. In this scenario, who does not have an incentive to push back from the gate as early as possible? Check all that apply.

The alternatives are ranked based on the initial cost of the alternate. The first is do nothing, the second is alternate 1, and the third is alternate 2.

The incremental benefit–cost ratio (BC) between the initial alternate, do nothing, and the new alternate 1 can be calculated as follows.

BC=B1−DB1C1(i(1+i)n1(1+i)n1−1)+AM1=520,000−90,0001,200,000(0.08(1+0.08)10(1+0.08)10−1)+80,000=430,0001,200,000(0.08(2.158925)2.158925−1)+80,000=430,0001,200,000(0.1727141.158925)+80,000=430,0001,200,000(0.149029)+80,000=430,000178,834.8+80,000=430,000258,834.8=1.66

The incremental benefit–cost ratio is 1.66. Since the incremental benefit–cost ratio is greater than 1, select the new alternate 1 and eliminate the initial alternate do nothing.

The incremental benefit–cost ratio (BC) between the initial alternate 1 and new alternate 2 can be calculated as follows:

BC=(B2−B1)−(DB2−DB1)(C2(i(1+i)n2(1+i)n2−1)+AM2)−C1(i(1+i)n1(1+i)n1−1)+AM1=(580,000−520,000)−(140,000−90,000)(2,000,000(0.08(1+0.08)20(1+0.08)20−1)+75,000)−(1,200,000(0.08(1+0.08)10(1+0.08)10−1)+80,000)=60,000−50,000(2,000,000(0.08(4.660957)4.660957−1)+75,000)−(1,200,000(0.08(2.158925)2.158925−1)+80,000)=10,000(2,000,000(0.3728773.660957)+75,000)−(1,200,000(0.1727141.158925)+80,000)=10,000(2,000,000(0.101852)+75,000)−(1,200,000(0.149029)+80,000)=10,000(203,704+75,000)−(178,834.8+80,000)=10,0002798,704−258,834.8=10,0002798,704−258,834.8=10,00019,869.2=0.503

The incremental benefit–cost ratio is 0.503. Since the incremental benefit–cost ratio is less than 1, select the initial alternate 1 and eliminate the new alternate 2.
