If it's 12% per year, compounded annually, then it is: 100 * (1 + 0.12)-2 = 79.72
As a rough guide to double any amount compounded annually, divide 70 by the interest rate. In this case that is 14 years.
You will have 5000 dollars × (1 + 8/100)18 = 19,980 dollars.

1,146.74 The interest is $1046.74 and the principal is $100.
You will have 5000 dollars × (1 + 8/100)18 = 19,980 dollars.
value = Amount × (1 + APR/100)^years → value = 500 × (1 + 7/100)^4 = 500 × 1.07^4 ≈ 655.40
