The $100 increases by 5%, or 1.05, every year, and to find the interest after two years, we use the formula above. His value after the first year raises to $105, and then again by 5%, which is 110.49.
If this question is: "true or false: the digit in the hundreds thousands place is 10times the value of the digit in the ten thousands place" then that would be true. I'm not really sure what you're asking... sorry :|
