Lou lewis borrows $10,000 to be completely repaid over 10 years at 8%. repayment of principal in the first year is

This is the concept of time value of money. To calculate the future value of the amount borrowed by Lewis we proceed as follows:
A=P(1+r/100)^n

A=amount in future
P=principle
r=rate
n=time
Thus;

A=10000(1+8/100)^1
A=10000(1.08)^1
A=$10,800
Therefore the repayment after the first year will be:
10800-10000
=$800

Yikes. that sucks dide
