Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function that best represents Samantha's account and how much does she have in savings after 5 years? Round your answer to the nearest dollar. Hint: Use the formula, f(x) = P(1 + r)x.

    Here are the answer options . f(x) = 500(1.4)x, $2,689 f(x) = 500(0.04)x, $512 f(x) = 500(1.04)x, $608 f(x) = 500(1.04)x, $527

    hints: r = interest rate = 0.04 P = principal amount = 500 your formula is f(x) = P(1+r)^x

    not quite, we still need to check whether it's C or D when x = 5, what does 500(1.04)^x = ?

    It is C. Because when i put 5 for the exponent it came out to be 608.32645. Correct?
