At a supermarket, a certain item has increased from 75 cents per pound to 81 cents per pound. What is the percent increase in the cost of the item

8%

Step-by-step explanation:

81-75=6

6/75 x 100 = 8%

y=x

Step-by-step explanation:

When the pentagon is reflected across y=x, all of its points are placed equally distant from the diagonal on one side as they are from the other. This causes the figure to turn 90 degrees instead of flipping like in any of the other reflections. Hope this helps!
