Luis invests $1000 into an account that accumulates interest continuously with a force of interest (t) = 0.3 + 0.1t, where t measures the time in years, for 10 years. Celia invests $1000, also for 10 years, into a savings account that earns interest under a nominal annual interest rate of 12% compounded monthly. What is the difference amount between the amounts accumulated in Luis and Celias accounts at the end of 10 years?
