Solution

Step 1 :Given values are: Principal amount \(P = \$ 5100\), Annual interest rate \(r = 4.8 \% = 0.048\) in decimal, Number of times interest is compounded per year \(n = 4\), and Time in years \(t = 2\).

Step 2 :We calculate the future value using the compound interest formula \(A = P \times (1 + r/n)^{n \times t}\).

Step 3 :Substitute the given values into the formula, we get \(A = 5100 \times (1 + 0.048/4)^{4 \times 2}\).

Step 4 :Calculate the above expression to get the future value of the investment.

Step 5 :The future value of the investment is \$ 5610.66.

Step 6 :Round the future value to the nearest cent, we get \$ 5610.66.

Step 7 :Final Answer: The value of Tyra's investment after 2 years will be \(\boxed{\$ 5610.66}\).
