Answer:
$7393.78
Explanation:
The formula for the value of Kelly's investment is ...
V = P(1 +r/n)^(nt)
where P is the principal invested (5000), r is the interest rate (.049), and t is the number of years (8). n is the number of times per year interest is compounded. When compounding is monthly, n=12.
Filling in the numbers, we find ...
V = $5000·(1 +.049/12)^(12·8) ≈ $7393.78
Kelly's investment will be worth $7393.78 in 8 years.
