  • 62. You multiplied .9 by 11,500 but it should have been multiplied by 11,550 giving you $10,395.

  • That is what I got as well: $10,395

  • Well this is boring I'm gonna go the the toaster how to make love and destroy it!!!

    LOL!!!

  • He got that right!

  • I think that last explanation was a tad confusing. There are 4 combinations of numbers that = 9 as you pointed out. Since there are 4 numbers in the first set and 5 in the second set there are 20 total combinations of numbers (4 x 5 = 20). 4/20=1/5.

  • yeah at 3:47 seconds on this video you copied 11,550 wrong and mistakenly wrote down 11,500..

    anyways, nothing you can do about it now..

    btw, your smart, i wish i could think as fast as you. Thx for the videos.

  • yeah he missed 50 when he multiplied by .9, but he is human, and what I really appreciate is the method to approach it, I got the right answer as well but I did little bit more steps. we just need to watch out the trap answers.

  • Sal,

    Problem 63 should be choice B.
