Bill has just returned from a duck hunting trip. He brought home eight ducks. Bill’s friend, John, disapproves of duck hunting, and to discourage Bill from further hunting, John presented him with the following cost estimate per duck:

Required:

1. Assuming the duck hunting trip Bill has just completed is typical, what costs are relevant to a decision as to whether Bill should go duck hunting again this season?

2. Suppose Bill gets lucky on his next hunting trip and shoots 8 ducks using the same amount of shotgun shells he used on his previous hunting trip to bag 8 ducks. How much would it have cost him to shoot the last two ducks?

SecuriCorp operates a fleet of armored cars that make scheduled pickups and deliveries in the Los Angeles area. The company is implementing an activity-based costing system that has four activity cost pools: Travel, Pickup and Delivery, Customer Service, and Other. The activity measures are miles for the Travel cost pool, number of pickups and deliveries for the Pickup and Delivery cost pool, and number of customers for the Customer Service cost pool. The Other cost pool has no activity measure because it is an organization-sustaining activity. The following costs will be assigned using the activity-based costing system:

The distribution of resource consumption across the activity cost pools is as follows:

Required:

Complete the first stage allocations of costs to activity cost pools.

The Oceanic Pacific fleet has just decided to use a pole-and- line method of fishing instead of gill netting to catch tuna. The latter method involves the use of miles of nets strung out across the ocean and therefore entraps other sea creatures besides tuna (e.g., porpoises, sea turtles). Concerns for endangered species was one reason for this decision, but perhaps more important was the fact that the major tuna canneries in the United States will no longer accept tuna caught by gill netting. Oceanic Pacific decided to conduct a new series of experiments to determine the amount of tuna that could be caught with different crew sizes. The results of these experiments follow.

a. Determine the point at which diminishing returns occur.

b. Indicate the points that delineate the three stages of production.

c. Suppose the market price of tuna is $3.50/pound. How many fishermen should the company use if the daily wage rate is a $100?

d. Suppose a glut in the market for tuna causes the price to fall to $2.75/pound. What effect would this have on the number of fishermen used per boat? Suppose the price rose to $5.00/pound. What effect would this have on its hiring decision?

e. If the firm realizes that to keep up with the demand for tuna, each of its boats must catch at least 1,000 pounds of fish per day. What should it consider doing? Why?

Break-even analysis attempts to determine the volume of sales necessary for a manufacturer to cover costs or to make revenue equal costs. It is helpful in setting prices, estimating profit or loss potentials, and determining the discretionary costs that should be incurred. The general formula for calculating break-even units is

Break-Even Units = Total Fixed Costs / (Unit Selling Price − Unit Variable Cost)

1. Use the formula to calculate how many cups of coffee an airport café would need to sell to break even if fixed costs are $6,000, a cup of coffee costs $0.50 to make, and each cup sells for $3.00.

For airlines, costs are mainly fixed, variable cost is negligible, and break-even is calculated for load factor instead of units. The formula for calculating break-even load factor is:

Break-Even Load Factor = Cost per Available Seat Mile / Yield per Passenger Mile

2. Given total operating cost of $1.6 million and 8.5 million available seat miles, calculate the cost per available seat mile (CASM).

3. What is the break-even load factor if CASM is $0.21 and the fare is $0.35 per mile? For this calculation, the yield is the same as the fare.

4. In Airline fare sales will reduce the yield. You can expect yield per passenger mile to drop about 10% for each month of fare sale. Calculate the break-even load factor if CASM is $0.21, regular fare is $0.35 per mile, and you are offering a two-month fare sale.

5. What impact might a 4% increase in compensation have on the break-even load factor for an airline?

Running Conditioning Knowledge Check

1. Find the max HR for a 29-year-old recreational runner. Then find their HR at zones 3 and 4, and ACSM’s recommendation for moderate and vigorous intensity.

2. Uncle Jake Peralta is just getting into running. He uses his thumb to measure his heart rate, and he seems to swing his arms across his chest consistently and complains he’s rotating his upper body too much. He also asks what he can do to progress his total weekly mileage. So far, he’s just been adding 5 miles to his mileage every week. What is he doing incorrectly with his technique, and what adjustments can be made? How can he properly increase his mileage?
   1. 
      
3. Aunt Gina Linetti has been recreationally running for a couple of months. However, she hasn’t changed her foot strike, always landing on the heel, and started complaining about shin splints. She warms up with shuttle runs, which leaves her out of breath before her actual workout. She mentions that during her workouts, she’ll sprint at her max for 30 seconds, and rest for 30 seconds, for a total five intervals. Recently, she’s been frustrated, wondering why her performance isn’t progressing. What is she doing incorrectly with her technique, and what adjustments can be made? How can the RAMP protocol be applied for her warm-ups? How can her work/rest ratio be modified to ensure optimal adaptations?

In Boston, due to the large amount of snowfall during winter of 2014-2015, the city has brought in several "snow dragons" to melt the snow.  
Model SND5400 is rated at:

•180 ton rated capacity per hour (Based on Latent Heat of Ice)
•No. 2 Fuel Oil or Diesel Fuel Type, Jet A Fuel
•Propane, and Natural Gas available for stationary units
•Fuel storage capacity of 3,000 US gallons
•Burner Output at 54,000,000 btu/hr  
•Measures 68' long x 11'6" wide x 12'4" high  


The USEPA states that there are 22,300 lb CO₂ emitted per 1000 gal of No. 2 fuel oil burned (AP-41 Table 1.3-12). The heat content of No. 2 fuel oil is 140 MMBtu/10³ gal (AP-42 Chapter 1.3).
(a) How many lbs of CO₂ are generated per hour when operating at maximum capacity?

(b) Calculate the lbs of CO₂ are generated per ton of snow melted.

(c) If the snow has a density of 24.97 lb/ft³, calculate the lbs of CO₂ are generated per ft ³ of snow melted.

(d) If the snow is 78 inches deep, and the road is 30 ft in width, calculate the lbs of CO₂ that are generated in clearing the snow from a length of road 10 ft.

(e) Based on the weighted average combined fuel economy of cars and light trucks in 2011, the amount of CO₂ emitted per mile driven was 0.92594 lbs CO₂/mile. Calculate the "equivalent miles" driven in clearing the snow from a length of road 10 ft (as in part (d)).
