The simplified answer is 46/33.
There are 26 letters of the alphabet
you want 6-character passwords without repetitionthe first time you pick a letter, you pick from 26 lettersthe second time you pick a letter, you pick from 25 letters (no repetitions !)the third time you pick a letter, you pick from 24 letters, and so onthe answer is 26*25*24*23*22*21=165,765,600 passwords
450 + 64% = 738.
738 - 450 = 288
or
64% x 450 = 288
288 more children joined the league this year than last year.
The multiplier for decreasing by 40% is 0.60. Since we want to know what was reduced by 40% (0.60), we divide the new price by the multiplier:
840 / 0.6 = 1,400
So the original price was 1,400
