it should be around $224
For simple interest you get $10 a year total in the account for 2 years $220.The answer is arrived at by multiplying $200x1.05x1.05 (for compound interest).$200x1.05x1.05= $220.50

Multiply the principal (P) by the annual* interest rate as a decimal (r) and the time in years* (t). *The time period may be expressed in months, etc. For example, $2000 invested at 7% simple interest for 5 years: I = Prt = 2000x0.07x5 = 140x5 = $700.
The interest earned will fluctuate with the interest rate and type of account. As of March 2013 interest rates, the daily interest accrued would be approximately $21,918.
For a single period there is no difference between the two. However, in the case of longer periods, simple interest is calculated on the capital borrowed (or lent). For periods after the first, compound interest is calculated not only on the capital but also on the interest accrued during previous years.For example, if 200 is borrowed at 5% for 3 years, then with simple interest, it will be200*(1+0.05*3) = 230. The compounded value is 200*(1.05)^3 = 231.53[Note 0.05 and 1.05 are used because 5% = 0.05 and a number increased by 5% is equivalent to multiplying it by 1.05.]
Amount to Deposit (P) = ? Time (N) = 15 months or 1.25 years Rate of Interest (R) = 5 Interest Earned = 200 Formula for Interest = P * N * R / 100 Rearranging the formula we get: P = Interest * 100 / N * R = (200 * 100) / 1.25 * 5 = 20000 / 6.25 = 3200 If they want to earn 200 interest they must deposit 3200 as the amount for the certificate of deposit.

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
