please see attached question. according the website the correct answer is 'C' but I just cant get my head around it can you please explain why???
A. Tax INCREASE = Previous Tax * Increase Rate -- Nope, just a piece of the puzzle.
B. Seriously Silly. You cannot add 0.045 to cash. The units don't match.
C. Refer to A. New Tax = Old Tax + Tax Increase
D. Seriously Silly. What does £*£ mean? Pounds squared? Units problems.
Did you know you could throw out fake answers by simply examining the units? Very useful idea!
