Final answer:

To calculate the value of the investment after 2 years, use the formula for compound interest and substitute the given values. The principal sum, annual interest rate, and number of years are needed. The formula for compound interest is V = P(1 + r/n)^(nt).

Step-by-step explanation:

The value of the investment after 2 years can be calculated using the formula for compound interest:



V = P(1 + r/n)^(nt)



Where:

V is the future value

P is the principal sum

r is the annual interest rate (in decimal form)

n is the number of times interest is compounded per year

t is the number of years



In this case, the interest is compounded annually, so n = 1.



First, we need to calculate the value of the investment after 3 years:



V = 100(1 + 0.05/1)^(1*3) = 115



Then, we can calculate the value of the investment after 2 years:



V = 100(1 + 0.05/1)^(1*2) = 110.25
