To calculate the future value of Company Y's investment account on December 31, 2020, continuous compounding must be applied to the annual investments. Each year, a percentage of the sales is invested, and the sales are growing at a constant rate. The formula for continuously compounded interest can be utilized for determining the future value, and additional calculations are necessary to find out the total investment and the interest earned.

**Note:**
Make sure to apply the formula for continuous compounding correctly and round your answers to three decimal places as indicated for accurate results.
