Since the order matters Person A and B can be chosen as AB (A pres B vice pres) or BA (B president A Vice president)
When the order matters we are talking about permutations. How many permutations of 11 taken 2 at a time are there.
It can be written like this 11nPr 2
It means start at 11 and multiply by the next lower number
11 x 10 = 110 ways they can choose.
Extension of the concept:
If there had been three positions President, Vice President, and Treasurer
then it would be 11nPr3 or 11 x 10 x 9
Once again the answer to your problem is 110.
We first determine the cost of one pair, that is:
So, each pair of shoes cost $63.Now, we determine the value of the commission:
So, the commission for each pair of shoes is $10.71, now we multiply this by 3 times. That is:
So, the commission for the three pairs of shoes will give him $32.13.
