Answer:
C
Step-by-step explanation:
Compound interest is a practice of reinvesting the the principal amount and the interest earned instead of paying out the interest . With this method , the total value of money increases with time.
However , the value of the money (principal +interest ) in the first year sing this method is the same as the simple interest method.
If a money is worth 10% compounded annually . $1100 in one year is $1000 today.
Workings
Interest rate - 10%
One year value (100%+10%) - $1100
Current value = 100/110*1100
= $1000
