Which of the following is an example of conditional probability?
probability of getting an a on a test
probability of drawing a club from a deck of 52 cards
probability of hitting a home run
probability of hitting a home run, given that you didn't strike out

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

both equations and proportions are better.
