Problem 6.27
You wrote a piece of software that does a better job of allowing computers to network than any other program designed for this purpose. A large networking company wants to incorporate your software into their systems and is offering to pay you $502,000 today, plus $502,000 at the end of each of the following six years for permission to do this.

Present value $

Problem 7.16
Barbara is considering investing in a stock and is aware that the return on that investment is particularly sensitive to how the economy is performing.

Problem 8.24
Trevor Price bought 10-year bonds issued by Harvest Foods five years ago for $976.42. The bonds make semiannual coupon payments at a rate of 8.4 percent. If the current price of the bonds is $1,014.85, what is the yield that Trevor would earn by selling the bonds today? (Round intermediate calculations to 4 decimal places, e.g. 1.2514 and final answer to 2 decimal places, e.g. 15.25%.)
Effective annual yield ___%

Problem 9.15
The First Bank of Ellicott City has issued perpetual preferred stock with a $100 par value. The bank pays a quarterly dividend of $1.65 on this stock. What is the current price of this preferred stock given a required rate of return of 10.0 percent? (Round answer to 2 decimal places, e.g. 15.25.)
Current price

Sure, I can help you with those questions. Let's go through each problem one by one.

Problem 6.19:
To find the future value of the investment cash flows, you can use the formula for calculating the future value of a series of cash flows: FV = CF1(1 + r)^n + CF2(1 + r)^n-1 + ... + CFn(1 + r)^1, where FV is the future value, CF is the cash flow, r is the interest rate, and n is the number of periods.

In this case, the cash flows are $772,380, $776,008, $982,094, $818,400, $1,239,644, and $1,617,848. The interest rate is 9.56 percent, and the number of periods is 6 years.

Using the formula, you can calculate the future value as follows:
FV = $772,380(1 + 0.0956)^6 + $776,008(1 + 0.0956)^5 + $982,094(1 + 0.0956)^4 + $818,400(1 + 0.0956)^3 + $1,239,644(1 + 0.0956)^2 + $1,617,848(1 + 0.0956)^1

Simplifying this expression will give you the future value of the investment cash flows after 6 years.

Problem 6.27:
To find the present value of the cash flow stream, you can use the formula for calculating the present value of a series of cash flows: PV = CF1/(1 + r)^n + CF2/(1 + r)^(n-1) + ... + CFn/(1 + r)^1, where PV is the present value, CF is the cash flow, r is the interest rate, and n is the number of periods.

In this case, the cash flows are $502,000 for each of the next six years. The interest rate is 6 percent, and the number of periods is 6 years.

Using the formula, you can calculate the present value as follows:
PV = $502,000/(1 + 0.06)^1 + $502,000/(1 + 0.06)^2 + $502,000/(1 + 0.06)^3 + $502,000/(1 + 0.06)^4 + $502,000/(1 + 0.06)^5 + $502,000/(1 + 0.06)^6

Simplifying this expression will give you the present value of the cash flow stream.

Problem 7.16:
To find the expected return on Barbara's investment, you need to multiply each return by its corresponding probability and sum up the results.

In this case, the returns and probabilities are given in the table. Multiply each return by its probability, and then sum up the results.

Expected return = (0.7 * 25.00%) + (0.1 * 15.00%) + (0.1 * 10.00%) + (0.1 * -5.00%)

Problem 8.24:
To find the yield Trevor would earn by selling the bonds today, you can use the formula for calculating the yield: Yield = (Annual Coupon Payment + (Price at Maturity - Current Price) / Number of Years) / ((Price at Maturity + Current Price) / 2), where Annual Coupon Payment is the coupon payment per period, Price at Maturity is the face value of the bond, Current Price is the price at which Trevor would sell the bond today, and Number of Years is the remaining number of years until the bond matures.

In this case, the Annual Coupon Payment is 8.4 percent of $976.42 (half the face value of the bond), Price at Maturity is the face value of the bond, which is $1,000, Current Price is $1,014.85, and Number of Years is 10 - 5 = 5 years.

Using the formula, you can calculate the yield. Remember to convert the yield to a percentage.

Problem 9.15:
To find the current price of the preferred stock, you can use the formula for calculating the present value of a perpetuity: PV = CF / r, where PV is the present value, CF is the cash flow, and r is the required rate of return.

In this case, the cash flow is $1.65 per quarter, and the required rate of return is 10.0 percent. Since the cash flow is paid quarterly, you need to adjust the required rate of return to a quarterly basis.

Using the formula, you can calculate the current price of the preferred stock. Remember to round your answer to 2 decimal places.
