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/n)^(nt)
From there then it’s just a matter of plugging in the values from the information given in the question! We have P = 8000, r = 0.03, n = 365, t = 10, meaning
A = 8000(1 + 0.03/365)^(365*10)
A = 10798.74
Meaning that the investment at the end of August 3, 2017 should be worth $10,798.74
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 :)
