Direct variation or not a direct variation

y=5/x

not direct variation

Step-by-step explanation:

The equation for x and y in direct variation is

y = kx ← k is the constant of variation

y = is not in this form, thus not direct variation.

The equation for x and y varying inversely is

y = ← k is the constant of variation

y = is in this form and represents inverse variation

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 !
