Even though she had more fish than she knew what to do with, she decided to go fishing again the next day. And she caught exactly 40% of what she caught the day before. Which was still a lot of fish.
She continued fishing every day. And every day she caught exactly 40% of what she caught the previous day.
If she continued fishing every day for twenty years, how many pounds of fish, total, would she catch? Please round to the nearest pound.

You need to know the first days catch!

This is a geometric series with a common ratio of r = 40% = 0.4. You haven't said how much she caught the first day, but the total amount after an infiinite period of time would be a / (1 - r), where a is the amount caught on the first day. That equates to a / (1 - 0.4) = a / 0.6 = 5a/3. If she goes fishing every day for twenty years, that might as well be an infinite series.
