Much To Your Surprise, You Were Selected To Appear On TV

Much To Your Surprise You Were Selected To Appear On The Tv

Question 1: Much to your surprise, you were selected to appear on the TV show, "The Price is Right." As a result of your prowess in identifying how many rolls of toilet paper an average American family keeps on hand, you win the opportunity to choose one of the following: $2,000 today, $10,000 in 10 years, or $31,000 in 29 years. Assuming you can earn 16% on your money, which should you choose? If you are offered $10,000 in ten years and can earn 16% on your money, what is the present value of $10,000?

Paper For Above instruction

To determine which of the options is most financially advantageous, we need to evaluate the present value (PV) of future sums considering a 16% annual return, and compare it with the immediate cash offer. The present value calculation is crucial for assessing the value of future money in today's terms, especially when deciding between receiving immediate versus future sums.

First, let's evaluate the present value of the $10,000 to be received in 10 years. The PV formula is:

PV = FV / (1 + r)^n

Where:

  • FV = future value = $10,000
  • r = interest rate = 16% or 0.16
  • n = number of periods = 10

Calculating:

PV = $10,000 / (1 + 0.16)^10 ≈ $10,000 / (1.16)^10

PV ≈ $10,000 / 4.441

PV ≈ $2,253.56

Next, repeat this calculation for the $31,000 received in 29 years:

  • FV = $31,000
  • n = 29

Calculating:

PV = $31,000 / (1.16)^29 ≈ $31,000 / 221.212

PV ≈ $139.94

Comparing all options:

  • Today: $2,000
  • In 10 years: approximately $2,253.56
  • In 29 years: approximately $139.94

The best financial choice in present value terms is to take the $10,000 offered in 10 years, since its PV ($2,253.56) exceeds the immediate $2,000 offer and the present value of the $31,000 in 29 years. Therefore, choosing the $10,000 in 10 years maximizes your wealth based on the 16% discount rate.

Question 2: Future Value Calculations

To find the future value (FV) of an annual series of payments compounded annually, we use the Future Value of an Ordinary Annuity formula:

FV = P * [((1 + r)^n - 1) / r]

Where:

  • P = annual payment
  • r = interest rate per period
  • n = number of periods

Future value of $500 for nine years at 11%

Given P = $500, r = 0.11, n = 9

FV = 500 * [((1 + 0.11)^9 - 1) / 0.11]

FV = 500 * [(2.580 - 1) / 0.11]

FV = 500 [1.580 / 0.11] ≈ 500 14.364

FV ≈ $7,182.00

Future value of $900 for nine years at 11%

Given P = $900, r = 0.11, n = 9

FV = 900 * [((1 + 0.11)^9 - 1) / 0.11]

FV = 900 [1.580 / 0.11] ≈ 900 14.364

FV ≈ $12,927.60

Question 3: Present Value of a Growing Perpetuity

The present value (PV) of a growing perpetuity is calculated using the formula:

PV = C / (r - g)

Where:

  • C = cash flow at time 1 = $80,000
  • r = discount rate = 9% or 0.09
  • g = growth rate = 7% or 0.07

Substituting values:

PV = 80,000 / (0.09 - 0.07) = 80,000 / 0.02 = $4,000,000

Therefore, the present value of this perpetuity is $4 million, assuming the cash flow grows at a rate less than the discount rate to ensure the PV is finite. If growth exceeds the discount rate, the PV would tend toward infinity, making the valuation meaningless.

Question 4: Present Value of a Perpetuity

The present value of a perpetuity is calculated using:

PV = C / r

Where:

  • C = annual cash flow = $650
  • r = discount rate = 12% or 0.12

Calculating:

PV = 650 / 0.12 ≈ $5,416.67

Question 5: Future Value and Present Value of a Series of Cash Flows

To find how much must be deposited today to enable withdrawals as specified, we need to determine the present value of the sequence of future cash flows, then discount that back to the present.

First, calculate the present value at year 11 of the future withdrawals:

  • Withdrawals from periods 11 through 18 consist of:
  • $9,000 at periods 11, 12, 13, 14, 15, 16, 17, 18
  • plus an $18,000 withdrawal at period 18

The present value at year 10 (just before year 11) of these cash flows, discounted at 8%, is as follows:

For the annuity of $9,000 over 8 years (periods 11-18), the PV at year 10 is:

PV of annuity = P * [1 - (1 + r)^-n] / r

Here, n = 8, P = $9,000, r = 0.08

PV (at year 10) of this annuity = 9,000 * [1 - (1 + 0.08)^-8] / 0.08

= 9,000 * [1 - 1 / (1.08)^8] / 0.08

= 9,000 * [1 - 1 / 1.8509] / 0.08

= 9,000 * [1 - 0.5403] / 0.08

= 9,000 0.4597 / 0.08 ≈ 9,000 5.746

≈ $51,714.50

Next, calculate the present value of the $18,000 received at period 18 (which is 8 years from year 10):

PV = FV / (1 + r)^n

= 18,000 / (1.08)^8 ≈ 18,000 / 1.8509 ≈ $9,713.64

Sum of present values at year 10:

Total PV at year 10 = $51,714.50 + $9,713.64 ≈ $61,428.14

Finally, discount this amount back to present (year 0):

PV today = $61,428.14 / (1 + 0.08)^11 ≈ $61,428.14 / 2.468

PV today ≈ $24,899.82

Therefore, the amount that must be deposited today to facilitate these future withdrawals, considering the 8% interest rate, is approximately $24,900.
