You plant a tree that is 36 inches tall. after one year, the tree is 43 inches tall. which expression describes the percent of increase in the tree's height?

a. 36/43 x 100
b.43-36/43
c.43-36/36 x 100
d.43-36/43 x 100

C  (43-36)/36 * 100

Step-by-step explanation:

The initial value is 36 inches

new value = 43

Percent increase is  (new - original)/ original * 100

                                  (43-36)/36 * 100

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 !
