Derek has the opportunity to buy a money machine today. The money machine will pay Derek $20,249.00 exactly 9.00 years from today. Assuming that Derek believes the appropriate discount rate is 10.00%, how much is he willing to pay for this money machine?

1 answer

To find out how much Derek is willing to pay for the money machine today, we need to calculate the present value (PV) of the future cash flow of $20,249.00 received in 9 years, discounted at a rate of 10.00%.

The formula for calculating the present value of a future cash flow is:

\[ PV = \frac{FV}{(1 + r)^n} \]

Where:

  • \( PV \) = Present Value
  • \( FV \) = Future Value ($20,249.00)
  • \( r \) = discount rate (10% or 0.10)
  • \( n \) = number of years until the cash flow is received (9 years)

Now, we can plug in the values:

\[ PV = \frac{20249}{(1 + 0.10)^9} \] \[ PV = \frac{20249}{(1.10)^9} \]

First, calculate \( (1.10)^9 \):

\[ (1.10)^9 \approx 2.3579477 \]

Now, substitute this value back into the present value formula:

\[ PV = \frac{20249}{2.3579477} \approx 8585.70 \]

Thus, the present value of the money machine is approximately $8,585.70.

Therefore, Derek should be willing to pay about $8,585.70 for the money machine today.
