Final answer:
Janice needs to annually deposit approximately $2,234 into an account with a 10% interest rate compounded annually to have $15,000 in 5 years for her parents' cruise.
Step-by-step explanation:
The question asks how much Janice must deposit annually into an account with a 10% interest rate compounded annually to accumulate $15,000 in 5 years. To solve this, we can use the future value of an annuity formula FV = P * (((1 + r)^n - 1) / r), where FV is the future value, P is the annual payment, r is the interest rate per period, and n is the number of periods.
Solving for P, we have P = FV / (((1 + r)^n - 1) / r). Substituting the given values, P = 15,000 / (((1 + 0.10)^5 - 1) / 0.10). Doing the calculations, Janice needs to deposit approximately $2,234 each year.
Thus, the answer to how much Janice must deposit annually is $2,234.
