Five years ago, a company was considering the purchase of 74 new diesel trucks that were 15.13% more fuel-efficient than the ones the firm is now using. The company uses an average of 10 million gallons of diesel fuel per year at a price of $1.25 per gallon. If the company manages to save on fuel costs, it will save $1.875 million per year (1.5 million gallons at $1.25 per gallon). On this basis, fuel efficiency would save more money as the price of diesel fuel rises (at $1.35 per gallon, the firm would save $2.025 million in total if he buys the new trucks).

Consider two possible forecasts, each of which has an equal chance of being realized. Under assumption #1, diesel prices will stay relatively low; under assumption #2, diesel prices will rise considerably. The 74 new trucks will cost the firm $5 million. Depreciation will be 25.35% in year 1, 38.81% in year 2, and 36.55% in year 3. The firm is in a 39% income tax bracket and uses a 10% cost of capital for cash flow valuation purposes. Interest on debt is ignored. In addition, consider the following forecasts:

Forecast for assumption #1 (low fuel prices):

Required: Calculate the percentage change on the basis that an increase would take place from the NPV under assumption #1 to the probability-weighted (expected) NPV.

Answer% Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places (for example: 28.31%).

Note: The educational purpose of this problem targets the students’ ability to read + follow instructions.

Further Information (solution steps):

• Step (1): Calculate the annual expected price of diesel per gallon under each assumption, based on the probabilities outlined in the inputs section.

• Step (2): Using the annual expected fuel prices calculated in step (1), determine the increase in annual savings created by the proposed efficiency for each assumption.

• Step (3): Find the increased cash flow after taxes (CFAT) for both forecasts, based on the annual increase in fuel savings determined in step (2) as the increase in earnings before depreciation and taxes (EBDT), and the starting point from which profit is calculated for each assumption. As part of this step, you must establish annual depreciation (remember: depreciation is a noncash charge).

• Step (4): Considering the increased annual CFAT produced in step (3), calculate the NPV of the truck purchases for each assumption, based on the discount rate (cost of capital) indicated in the inputs section

• Step (5): In view of the outcomes produced in step (4), estimate the combined NPV weighed by the probability of each assumption.

• Step (6): Finally, calculate the percentage difference hypothesizing that an increase took place starting from the NPV for assumption #1 to the combined NPV worked out in step (5).

A 74-year-old man was admitted to a nursing home for the first time following hospitalization for an exacerbation from heart failure, which is being controlled with Lasix 120 mg a day at this time. While the patient was in the hospital, he fell on the way to the bathroom and sustained a fractured hip, which required an ORIF. He had spinal anesthesia for the fractured hip.

He lives alone at home and has three grown children who live in the same town. He would like to return home. He has been widowed for 9 months. He had been married for 50 years and worked outside the home as a banker. His wife prepared all his meals for him.

During hospitalization, his dietary intake was 10 to 20% of the food provided. He did not receive any food from family or friends to offset his hospital meals. Since admission to the nursing home two days ago, he has eaten only 10% of his diet, which was a low-NA diet, mechanical soft (due to improperly fitting dentures). He was a 20-year smoker, one pack a day. He reports minimum alcohol intake.

He states that since his wife died, he has been leading a sedentary lifestyle, not going out very often. He reports no “real exercise” activities.

The Medications Discharge from Hospital:

• Digoxin 0.125 mg oral every morning
• Lasix 40 mg tid
• Nu-Iron 150 mg oral daily
• Hydrocodone and acetaminophen tablets, 5 mg/500 mg for pain
