If the interest is simple interest, then the value is
100 [ 1 + (10 x 0.11) ] = 100 (1 + 1.1) = 100 x 2.1 = $210 .
If the interest is compound interest, and is compounded annually, then the value is
100 (1 + 0.11)¹⁰ = 100 (2.8394) = $283.94 .
If the interest is compound interest, and is compounded monthly, then the value is
100 (1 + 0.11/12)¹²⁰ = 100 (2.9891) = $298.91 .
