The compound interest formula is:
A+=+P%281+%2B+%28r%2Fn%29%29%5E%28nt%29
Where A is the final amount, P is the principal amount, r is the rate in decimal form, n is the number of times per year the interest is compounded, and t is the number of years.
So in part a), we have r = 0.08, n = 1, t = 5, and we want A to be 6000 since that is the desired amount at the end of the 5 years. So we need to solve for P.
6000+=+P%281+%2B+%280.08%2F1%29%29%5E%281%2A5%29
6000+=+P%281.08%29%5E5
P+=+4083.50
Note that we round to two decimal places since this is money. So if you want $6,000 at the end of 5 years, you need to start with $4,083.50.
For part b), the $15,000 is our P, our initial amount. And t is 4. So we are solving for A.
A+=+15000%281+%2B+%280.08%2F1%29%29%5E%281%2A4%29
A+=+15000%281.08%29%5E4
A+=+20407.33
So at the end of 4 years, you will have to repay $20,407.33.
