Final answer:
Tammy's investment of $3,530 at a 14% annual return over 10 years would grow to approximately $9,743 when rounded to the nearest dollar, using the formula for compound interest.
Step-by-step explanation:
To calculate the future value of Tammy's investment, we can use the formula for compound interest, which is A = P(1 + r/n)^(nt). Since Tammy is investing $3,530 at a 14% annual return, compounded once a year (n=1) for 10 years (t=10), the calculation will be as follows:
A = 3530(1 + 0.14/1)^(1*10) = 3530(1.14)^10
Using a calculator to compute this, we find:
A ≈ 3530 * (2.75811) ≈ 9743.1977
Rounded to the nearest dollar, the future value of Tammy's investment would be $9,743.
