How do you calculate the number of possible solutions for an inequation?Example: if I have an inequality 0 < X1 < X2 < X3 < 30 where Xn is an integer. And what do I do when the numbers are less than or equal to (≤)?Are there general formulas for both of them?

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 !
