If s denotes the length of the arc of a circle of radius r subtended by a central angle \theta , find the missing quantity.

s = 7.02 meters, \theta = 2.6 radians, r = ?
a. 0.37 m
b. 3.6 m
c. 1.35 m
d. 2.7 m

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 !
