Using the 6% column of the compound interest table, the compound amount for 9 years is found to be 1.6895. Multiply this amount times the principle to calculate the amount that will be repaid. $1.6895\times76,000=128,402$ dollars The interest is the difference between the amount to be repaid and the principle. $128,402-76,000=52,402$ dollars
