You start with finding #10%# of #90.#
#$90 * .1 = $9#
You add the money and the interest to get #$99# for the first year. However, the next year is different. It's compound interest, so you have to multiply #10%# by #$99#.
#$99 * .1 = $9.90#
#$99+ $9.90 = $108.90#
The total would then be #$108.90#.

That's it! Remember to keep on learning!
