The power function y = ax^b is shown graphed below. Which of the following must be true about the values
of a and b?
(1) a must be negative and b must be even
(2) a must be even and b must be positive
(3) a must be positive and b must be even
(4) a must be odd and b must be positive

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 !
