Answer 1

Answer: If interest rate was 4%= $180.09. If interest rate was 8%= $317.22

Step-by-step explanation:

Assuming that the aboriginal trackers were promised the $100 at the beginning of the year 1880 and the claim was also made at the beginning of the year 1995.

Number of years from 1880-1995 = 15 years

If the interest rate was 4%

= 100*(1+4%)^15

= $180.09

If the interest rate was 8%

= 100*(1+8%)^15

= $317.22
