Math Problem Statement

plese solve this question I have been struggling with for the past few days:

A math tee shirt business is expected to generate $17,000 in revenue per year for the next 5 years. If the income is reinvested in the business at a rate of 3% per year compounded continuously, determine the future value of this income stream at the end of 5 years.

Solution

The problem asks to determine the future value of a business generating $17,000 in revenue per year over the next 5 years, with the revenue being reinvested at an interest rate of 3% per year, compounded continuously.

The formula provided in the image to calculate the future value is:

FV=17000×10.03×(1e0.15)e0.15FV = 17000 \times \frac{1}{0.03} \times \left( 1 - e^{-0.15} \right) e^{0.15}

Where:

  • 17000 is the yearly revenue.
  • 0.030.03 is the continuous compounding rate (3%).
  • e0.15e^{-0.15} represents e0.03×5e^{-0.03 \times 5}, where 5 is the number of years.
  • e0.15e^{0.15} is e0.03×5e^{0.03 \times 5}.

Let's break this down and compute it step by step:

  1. Compute e0.15e^{-0.15}: e0.150.8607e^{-0.15} \approx 0.8607

  2. Compute 1e0.151 - e^{-0.15}: 10.8607=0.13931 - 0.8607 = 0.1393

  3. Multiply by e0.15e^{0.15} (since e0.151.1618e^{0.15} \approx 1.1618): 0.1393×1.1618=0.16190.1393 \times 1.1618 = 0.1619

  4. Now, multiply by 10.03\frac{1}{0.03}: 0.1619×10.03=5.39670.1619 \times \frac{1}{0.03} = 5.3967

  5. Finally, multiply by 17000: 17000×5.3967=91,744.0717000 \times 5.3967 = 91,744.07

Thus, the future value of the revenue stream is approximately $91,744.07.

Would you like further clarification or details on any step? Let me know if you'd like to explore this in more depth.

Here are 5 related questions to consider:

  1. How does continuous compounding differ from simple compounding?
  2. What happens if the interest rate increases from 3% to 4%?
  3. How would the result change if the revenue was not reinvested?
  4. What is the significance of the exponential term e0.15e^{-0.15}?
  5. How can we model this problem for non-continuous reinvestment?

Tip: When dealing with continuously compounded interest, always remember that the formula involves the exponential function erte^{rt}, which grows faster than simple compounding!
