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?

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?

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:

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)).

Several months ago, Ayers Industries Inc. experienced a hazardous materials spill at one of its plants. As a result, the Environmental Protection Agency (EPA) fined the company $430,000. The company is contesting the fine. In addition, an employee is seeking $540,000 in damages related to the spill. Lastly, a homeowner has sued the company for $270,000. The homeowner lives 30 miles from the plant, but believes that the incident has reduced the home's resale value by $270,000.

Ayers’ legal counsel believes that it is probable that the EPA fine will stand. In addition, counsel indicates that an out-of-court settlement of $230,000 has recently been reached with the employee. The final papers will be signed next week. Counsel believes that the homeowner's case is much weaker and will be decided in favor of Ayers. Other litigation related to the spill is possible, but the damage amounts are uncertain.

To illustrate the effects of driving under the influence of alcohol, a police officer brought a DUI simulator to a local high school. Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine teenagers, the time (in seconds) required to bring the vehicle to a stop from a speed of 60 miles per hour was recorded. Complete parts (a) and (b). Note: A normal probability plot and boxplot of the data indicate that the differences are appromixately normally distributed with no outliers.

(a) Whether the student had unimpaired vision or wore goggles first was randomly selected. Why is this a good idea in designing the experiment?

A)This is a good idea in designing the experiment because it controls for any "learning" that may occur in using the simulator.

B)This is a good idea in designing the experiment because reaction times are different

C) This is a good idea in designing the experiment because the sample size is not large enough

(b) Use a 95% confidence interval to test if there is a difference in braking time with impaired vision and normal vision where the differences are computed as "impaired minus normal"

The lower bound is ______

The upper bound is _______

(Round to the nearest thousandth as needed)

State the appropriate conclusion

A)There is sufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision
