Final answer:
The future value of the investments, calculated using continuous compounding at various interest rates and timelines, results in $3,926.75 for 9 percent over 5 years, $3,805.25 for 7 percent over 6 years, $3,580.50 for 4 percent over 9 years, and $4,555.25 for 10 percent over 6 years.
Step-by-step explanation:
To calculate the future value of an investment with continuous compounding, we use the formula FV = Pert, where P is the principal, e is the base of the natural logarithm (approximately equal to 2.71828), r is the annual interest rate (expressed as a decimal), and t is the time in years.
Calculations:
Make sure all calculations are done without rounding intermediate steps, but the final answers should be rounded to two decimal places.
