A clever Usul figured out a great way to catch fish in the Underwater Fishing Cavern. (However, in the spirit of fairness, we won't reveal her secret!) The first day she went fishing, she caught exactly 31416 pounds of fish! 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.
My answer goes wayyyyy below one, after three years my comp gets 0 pounds so my guess if we had to round up: 1 pound
52360 ^Ok, I confirmed it. Because you were in the first 250 to guess correctly, you also have been awarded a Pteri Seed Cake, and receive a trophy and the Lenny Conundrum avatar! ^Last weeks finally got me my trophy! Answer was Ogrin.
How could the answer be higher than the original amount of fish? It says 40% of yesterdays catch meaning a less amount
probably not...it was an equation problem... the sum of an infinite series is a/(1-r) ..."a" being the first term (31416) and "r" being the rate (.4) I've got a final over this stuff tomorrow :cry: ...
are you that smart/bored to figure the total answer? @@ that would take my hair away from me to figure that out, unless u use a calculator... darn im dumb... lol
a1 (1 - r^n) = Sum of all numbers up to (n) (1 - r) Where a1 = 31416 (first number in series) n = 7305 (number to go to i.e 20 years in days) r = 0.4 (common ratio (i.e what you do to a number to get the next in the series.) in this case 40% of the previous number = 0.4) And that gives you what the rest have been getting 52360. ^-^ Ahh good old statistics. I had this last year in my AS levels. Hated it.
Thnx! I've already entered it in. If i was in statistic i would be able to this...but I just finished Geometry I in my school...
