Correct Answer: 2315.25

Explanation: The compound interest formula is:  where:

- A is the amount of money accumulated after n years, including interest.

- P is the principal amount (the initial amount of money).

- r is the annual interest rate (in decimal).

- n is the number of times that interest is compounded per year.

- t is the time the money is invested for in years.

Given:

- Principal P=2000 

- Annual interest rate r = 5% = 0.05 (since 5% as a decimal is 0.05)

- Interest is compounded yearly, so n=1 

- Time t=3 years Plugging these values into the formula, we get:  

Simplifying the expression:  A = 2000×

Now, calculate  and multiply the result by 2000 to find the total amount in the account after 3 years. After calculating, we find that Jen will have 2315.25 in the account after 3 years.
