Here is how you calculate this. Each year, the money increases by a factor of 1.0725. That is 1 for the original capital, plus the 7.25% or 7.25/100. So, after 8 years, you will have:
3900 x 1.0725 x 1.0725 x ... x 1.0725 = 3900 x 1.07258.

Total value = 20000*(1.06)2 = 22472 So interest = 2472
Inserting values into the formula for compound interest, you get:4100 * (1 + 3.75/100) to the power 6.
Compound Interest = P(1+r/100n)(nt) P = Original Investment r = Interest Rate n = How often the interest is compounded per year t = Number of years Interest = 200(1+6/100)6 = 200(1.06)6 =$283.70
500 invested for 5 years at 7% interest compounded annually becomes 701.28
"Compounded annually" means that the interest is added once a year.
Twice

Once.
Assuming that 1.5 refers to 1.5% and that the interest is compounded annually, the principal is 893.30

Interest = 2472
At the end of the year the interest is deposited in the account. The next year the interest is figured on the principal plus last year's interest.
If the interest is compounded annually, then the first interest payment isn't added until the end of the first year. Until then, the investment is worth exactly $15,000.00 .

If the interest is simple interest, then the value at the end of 5 years is 1.3 times the initial investment. If the interest is compounded annually, then the value at the end of 5 years is 1.3382 times the initial investment. If the interest is compounded monthly, then the value at the end of 5 years is 1.3489 times the initial investment.
The amount, P, is the principal. If the rate is r% compounded annually for y years, then the total interest earned is P*[(1 + r/100)^y - 1]
