An arts academy requires there to be 4 teachers for every 72 students and 5 tutors for every 45 students. How many students does the academy have per teacher? Per tutor? How many
tutors does the academy need if it has 90 students?
The academy has students per teacher.

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.
