Howell Petroleum, Inc., is trying to evaluate a generation project with the following cash flows: Year Cash Flow 0 –$40,500,000 1 62,500,000 2 – 15,500,000

a. If the company requires a return of 11 percent on its investments, what is the NPV of the project? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) NPV$

b. Compute the IRRs for this project. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16. Enter the larger IRR in the first answer box and the smaller IRR in the second answer box. If you can only calculate one IRR, enter it in both boxes to receive partial credit. A negative answer should have a minus sign.) Internal rate of return % Internal rate of return %"

The taxi-company-outline project defines a Demo class to create a pair of PassengerSource and TaxiCompany objects. Create a Demo object and try its pickupTest method. Why is the TaxiCompany object unable to grant a pickup request at this stage?

An analyst for a new company used the first three years of revenue data to project future revenue for the company. The analyst predicts the function

$$f(x) = -2x^5 + 6x^4 - x^3 + 5x^2 + 6x + 50$$

will give the revenue after x years. Should the CEO expect the company to be successful? Explain.

A recent sensitivity analysis of a public works project indicates that the expected present worth is $83,000. If there is a 20% chance that the PW will be the pessimistic one of$45,000 and 50% chance that it will be the most likely one of $72,000, the optimistic PW is closest to: (a)$89,520 (b) $118,380 (c)$126,670 (d) $138,540

Underline the word in parentheses that correctly completes the sentence.

Example 1. For this project, you must split up into (to, too, $\underline{\text{two}}$) groups.

First United Bank Inc. is evaluating three capital investment projects using the net present value method. Relevant data related to the projects are summarized as follows:

$$\begin{array}{lrr} &\textbf{Branch}& \textbf{Computer}&\textbf{ATM }\\ &\textbf{Office}& \textbf{System}& \textbf{Kiosk} \\ &\textbf{Expansion}& \textbf{Upgrade}& \textbf{Expansion}\\ \hline \text{Amount to be invested . . . . . . . . . . . . .} & \$420,000& \$350,000& \$520,000\\ \text{Annual net cash flows:}\\ \quad \text{Year 1 . . . . . . . . . . . . . . . . . . . . . . . . }&200,000& 190,000& 275,000\\ \quad \text{Year 2 . . . . . . . . . . . . . . . . . . . . . . . . }&160,000& 180,000& 250,000\\ \quad \text{Year 3 . . . . . . . . . . . . . . . . . . . . . . . . }& 160,000& 170,000& 250,000\\ \end{array}$$

Instructions

1. Assuming that the desired rate of return is 15%, prepare a net present value analysis for each project. Use the present value of $1 table appearing in this chapter.
2. Determine a present value index for each project. Round to two decimal places.
3. Which project offers the largest amount of present value per dollar of investment? Explain.

You wish to project the image of a slide on a screen $9.00 \mathrm{~m}$ from the lens of a slide projector. (b) If the dimensions of the picture on a $35-\mathrm{mm}$ color slide are $24 \mathrm{~mm} \times$ $36 \mathrm{~mm}$, what is the minimum size of the projector screen required to accommodate the image?

A Pew Internet and American Life Project survey found that 392 of 799 randomly selected teens reported texting with their friends every day. Calculate and interpret a 95% confidence interval for the population proportion p that would report texting with their friends every day.

In a pilot project, a rural township is given recycling bins for separating and storing recyclable products. The cost C (in dollars) of supplying bins to p% of the population is given by $C=\frac{25,000 p}{100-p}, \quad 0 \leq p<100$. Use a graphing utility to graph the cost function.

Underline the introductory element in each of the following sentences. Then , add commas where necessary.

Example 1. $\underline{\text{During the course of this project}}$, we will see many interesting things.

8. Why what an incredible accomplishment!

In this project you will measure the angle a typical handicap access ramp makes with the horizontal.

Based on handicap access ramps you have seen, make a conjecture about the angle these ramps make with the horizontal. Each member of your group should make his or her own conjecture.
