Hello, thank you for taking the time to post your question!
The underlying formula that we want to use here for compound interest is
A = P(1 + r)^(t)
From there then it’s just a matter of plugging in the values from the information given in the question! We have P = 3400, r = 0.055, t = 11, meaning
A = 3400(1 + 0.055)^11
A = 6127.11
Rounding to the nearest dollar, the investment will be worth $6,127 after 11 years
I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)
