Answer:
$41.69
Step-by-step explanation:
The computation of the selling price of the each pair of slacks is as follows:
Given that
Cost = $19.36 per pair
Markup = $22.33
As we know that
Markup = Sell Price - Cost
So,
Sell Price = Cost + Markup
= $19.36 + $22.33
= $41.69
Hence, the selling price is $41.69
The expression 3P2 can also be read as "permutation of 3 taken 2". This represents the number of ways in which the 3 items are arranged with the emphasis on the arrangement of the first two other items.
