The correct answer is that the interest earned in 6 months for an investment of $ 4,000.00 at an interest rate of 4.25% per year was $ 85.

I = P * i * n       where:     I = earned interest,        P = capital

i = annual interest,         n = time

I =?    P = $ 4,000.00      i = 4.25%      n = 1/2 years

I = $ 4,000.00 * 0.0425 * 0.5

I = $ 85.00
