Answer:
677,890.77 dollars.
Explanation:
To find the future value of the income stream, we can use the continuous compound interest formula:
FV = Pe^(rt)
Where FV is the future value, P is the present value, e is Euler's number (approximately 2.71828), r is the interest rate, and t is the time period.
In this case, the present value (P) is the revenue generated at a rate of R(t) = 150000 dollars/year for 4 years, so:
P = 150000 dollars/year * 4 years = 600000 dollars
The interest rate (r) is 2.8%/year, or 0.028/year as a decimal. The time period (t) is also 4 years.
Substituting these values into the formula, we get:
FV = 600000 * e^(0.028*4)
FV = 677,890.77 dollars
Therefore, the future value of this income stream after 4 years with continuous compounding at an interest rate of 2.8% per year is 677,890.77 dollars.
