A Math Problem 2 Solve:

$6, 700 deposit, what is the interest earned after a year? How much is left in the bank

after three years?

Hint: rate=4%=0.04, principal=$6, 700,

Formulas: One Year Interest=rate x principal=___ x______=_______

Three Year Interest=rate xย  principal x time=___ x ____ x ____=_______

  1. Not a “blue” Monday when you make math fun . . . still don’t get the answers right, but at least it gives the gray matter a different kind of workout. Thanks, Ji! ๐Ÿ™‚

  2. I had once quite foolishly stated that I am a Math geek… So let’s see if I can answer your question here… Is it $7504?
    But I KNOW this is a trick question!! Which student ever has $6700 in a bank!!! ๐Ÿ˜‰

    Love your posts, Ji !! They are so colorful, pleasant to the eye, they take away the blues, and they always get me thinking ! ๐Ÿ™‚
    Many hugs…

  3. I am sure there is a trick here…”How much is left in the bank after three years?”…this question makes me think ??!!…and also because they earn interest on interest???? My answer would be $7536.59…but then, I’m not good with Math challenges! Thanks Ji…fun fun fun! x

      1. i used 7,600 at first, which does not match the number given in the question, the answer is incorrect.

        Now the above solution is CORRECT!

        thanks for reading!

  4. I quit doing math problems when I graduated from college!!! I wanted to use my Calculus book for target practice but my kids wouldn’t let me! !! (true story) But this is a neat idea for a post!!!

  5. lol make me realize i had forgotten all my math XD, and my dreadful math teacher in high school XD worksheets every single day =X T.T but tihnking back it kinds of help ๐Ÿ˜€

  6. If the student is Jade in her long gone student days, there will be no more money in the bank in less than two weeks, interests notwithstanding :-)))))
    Cool thing you got going on here! [clap clap clap]

  7. Wow!! After a long time Jingle. ๐Ÿ™‚
    My answers are $268 for the first one and $7504 for the second one.

  8. Oh my…it’s not even seven O’clock in the morning, I haven’t had my tea, and I’m pretty sure my eyes are not even focused yet. There is no way I can do that yet. But, as much as I would love to avoid it…I’m thinking I will be back to figure it out. These things have a tendency to bother me until I figure them out.

  9. What a perfect challenge for Blue Monday. I read and enjoyed you story above. I hope you have a wonderful day. Blessings…Mary

  10. I can see where you used math for Blue Mon. math will make you blue LOL , makes you think though !thanks for stopping by!

  11. Seriously, now it looks like I’m just copying when I say $268 for one year of interest and after three years there is $7504 in the bank.

    Great blue math question!

  12. Ouch! That sprained my brain – I have to be careful about encounters with unexpected math early in the morning!

  13. Love your blue images here! And I love a challenge, puzzle…of any kind… but I am so very late, late, late in my blog reading rounds…so, I am thankful that you helped us along with including the formulas :o)

    Blessings & Aloha!
    (If you get a chance, I’d love if you would stop by my place :o)

  14. Ouch. My brain is suffering some severe strain here. Math? An equation? ACCCKKK!!!!!!!

    I think the answer is two apples but I’m not 100% sure!

    Thanks for a really different link to Rainbow Summer School!

    You made me laugh. And wonder. And swear. Just a teeny bit.
