The grades on an exam are 82, 68, 93, 84, 79, 80, 36, 71, 63, 91, 67, 68, 96, 84, 77, 83, 89, 80, 86, 44, 73, 72 ,45, 75, 71, 68, 54, 59, 99, 60, 63 ,55, 87, 97, 95 ,67 (a) What is the range of this data set? (b) Draw a histogram with the first class interval of 30-39. (c) Identify the five number summary. (d) Find the mean and standard deviation. e) Find IQR

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 !
