Answer:

In fifteen years, Alexis would have 9200. In twenty years she would have 9600

Step-by-step explanation:

10% for interest of 8000= 80.

80 (interest for one year) * 15 (fifteen years)= 1200

1200 plus the original amount is 9200.

80 (interest for one year) * 20 ( twenty years)= 1600

1600 plus the original amount is 9600
