Using the formula for continuous compounding, F=Pe^rn, we will be able to determine the number of years it took P= 200 to become F= 350. We just substitute the given numbers into the equation, let F=350, P=200, and r=0.08. We will obtain n=7 years, which is the number of years for 200 to become 350.
