Please find attached the problem that I need help with.

Chapter 4. a. Find the FV of $1,000 invested to earn 10% annually 5 years from now. Answer this question by using a math formula and also by using the Excel function wizard. Inputs: Formula: Wizard (FV): PV = r = N = FV = PV(1+r)^N = 1000 10% 5 Note: When you use the wizard and fill in the menu items, the result is the formula you see on the formula line if you click on cell E12. Put the pointer on E12 and then click the function wizard (fx) to see the completed menu. Also, it is generally easiest to fill in the wizard menus by clicking on one of the menu slots to activate the cursor and then clicking on the cell where the item is given. Then, hit the tab key to move down to the next menu slot to continue filling out the dialog box. Experiment by changing the input values to see how quickly the output values change. b. Find the PV of $1,000 due in 5 years if the discount rate is 10% per year. Again, work the problem with a formula and also by using the function wizard. Inputs: FV = r = N = PV = FV/(1+r)^N = Formula: Wizard (PV): 1000 10% 5 Note: In the wizard's menu, use zero for Pmt because there are no periodic payments. Also, set the FV with a negative sign so that the PV will appear as a positive number. C. A security has a cost of $1,000 and will return $2,000 after 5 years. What rate of return does the security provide? Inputs: PV = FV = r = N = -1000 2000 ? 5 Wizard (Rate): Note: Use zero for Pmt since there are no periodic payments. Note that the PV is given a negative sign because it is an outflow (cost to buy the security). Also, note that you must scroll down the menu to complete the inputs. d. Suppose California's population is 30 million people, and its population is expected to grow by 2% per year. How long would it take for the population to double? Inputs: PV = FV = r = growth rate N = -30 60 2% ? Wizard (NPER function): = Years to double. e. Find the PV of an ordinary annuity that pays $1,000 at the end of each of the next 5 years if the interest rate is 15%. Then find the FV of that same annuity. Inputs: PMT = N= r = $ PV: Use function wizard (PV) PV = FV: Use function wizard (FV) 1,000 5 15% FV = f. How would the PV and FV of the above annuity change if it were an annuity due rather than an ordinary annuity? For the PV, each payment would be received one period sooner, hence would be discounted back one less year. This would make the PV larger. We can find the PV of the annuity due by finding the PV of an ordinary annuity and then multiplying it by (1 + r). PV annuity due = x = Exactly the same adjustment is made to find the FV of the annuity due. FV annuity due = x = g. What would the FV and the PV for parts a and c be if the interest rate were 10% with semiannual compounding rather than 10% with annual compounding? Part a. FV with semiannual compounding: Inputs: PV = r = N = Formula: FV = PV(1+r)^N = Wizard (FV): Orig. Inputs 1000 10% 5 New Inputs 1000 5% 10 Part c. PV with semiannual compounding: Orig. Inputs New Inputs To get the dialog box, click on fx, then Financial, then FV, then OK. Inputs: FV = r = N = 1000 10% 5 1000 5% 10 Formula: Wizard (PV): PV = FV/(1+r)^N = h. Find the PV and FV of an investment that makes the following end-of-year payments. The interest rate is 8%. Year 1 2 3 Payment 100 200 400 Rate = 8% To find the PV, use the NPV function: PV = Excel does not have a function for the sum of the future values for a set of uneven payments. Therefore, we must find this FV by some other method. Probably the easiest procedure is to simply compound each payment, then sum them, as is done below. Note that since the payments are received at the end of each year, the first payment is compounded for 2 years, the second for 1 year, and the third for 0 years. Year 1 2 3 Payment 100 200 400 x (1 + r)^(N-t) 1.17 1.08 1.00 = FV 116.64 216.00 400.00 Sum = An alternative procedure for finding the FV would be to find the PV of the series using the NPV function, then compound that amount, as is done below: PV = FV of PV = i. Suppose you bought a house and took out a mortgage for $50,000. The interest rate is 8%, and you must amortize the loan over 10 years with equal end-of-year payments. Set up an amortization schedule that shows the annual payments and the amount of each payment that repays the principal and the amount that constitutes interest expense to the borrower and interest income to the lender. Original amount of mortgage: Term of mortgage: 50000 10 Interest rate: 0.08 Annual payment (use PMT function): Year Beg.

What would the amortization schedule show now? Now we would have a 12 10 = 120-payment loan at a monthly rate of .08/12 = 0.666667%. The monthly payment would be: Month Beg.
