<u>Total options:</u>
c)
A to C, 20 ways
<u>Return to A with different ways:</u>
- (5 - 1)(4 - 1) = 4*3 = 12
<u>Total options:</u>
The answer is b when you plug it in
Ok, to show that she is incorrect we can use any other number in both equations and they will not be equal. the number she used does turn out equal but that does not mean the equations are equal.
