MathWizard likes to play a fun number trick on her friends. She tells them to think of a number. She then tells them to subtract their number from 2 and multiply the result by 5. To this product she tells them to add half the difference when 24 is subtracted from 12 times their original number.

(a) If I use the number 8 and follow MathWizard's steps, what number will I get?

Mmmmmm....that's a lot of stuff..LOL!!!

2 - 8  = - 6

-6 * 5 = -30

"  half the difference when 24 is subtracted from 12 times their original number."   translates to

(1/2) ( 8 * 12 - 24 ]  =    (1/2) [ 96 - 24 ]  = (1/2)(72) = 36

So

-30 + 36 =   Feb 20, 2019
