In 1880 five aboriginal trackers were each promised the equivalent of 100 Australian dollars for helping to
	capture the notorious outlaw Ned Kelley. In 1993 the granddaughters of two of the trackers claimed that
	this reward had not been paid. The Victorian prime minister stated that if this was true, the government
	would be happy to pay the $100. However, the granddaughters also claimed that they were entitled to
	compound interest. How much was each entitled to if the interest rate was 4%? What if it was 8%?
