5. A company invests $15,000.00 in an account that compounds interest annually. After two years, the account is worth $16,099.44. Use the function, where r is the annual interest rate, P is the principal, and A is the amount of money after t years. What is the interest rate of the account?

Question

1.04%
3.6%
5.4%
7.3%

Answer 1

We can use the formula A = P(1 + r)^t to solve for r. Plugging in the given values, we get:

16,099.44 = 15,000(1 + r)^2

Dividing both sides by 15,000 and taking the square root, we get:

sqrt(16,099.44/15,000) = 1 + r

r = 0.036 or 3.6%

Therefore, the interest rate of the account is 3.6%. Answer: \boxed{3.6\%}.
