Step 1 :Let's denote the principal amount as \(P\), which is Ghc5000.
Step 2 :The annual interest rate is denoted as \(r\), which is 0.15.
Step 3 :The number of times interest is compounded per year is denoted as \(n\), which is 4.
Step 4 :We calculate the total amount owed for each year using the formula for compound interest: \(A = P(1 + \frac{r}{n})^{nt}\).
Step 5 :We sum up the total amount owed for each of the four years.
Step 6 :Finally, we find that the total amount that Obuor will owe the loan company after his four year study is approximately \(\boxed{29294.02}\) Ghc.
