The market bought grapes for $0.87 a pound and sold them for $1.09 a pound. What is the percent for increace rounded to the near

Len [333]

So to find percent increase, you want to minus the difference in cost..

1.09- 0.87= .22...

now divide the difference by the original....

.22 ÷ .87 = .25287.....etc

now multiply that by 100...

.25287 × 100 = 25.287

now it says round to the nearest tenth so...

25.29% increase.

Can someone explain why the answer is D? i don't get how to do this :')

Join JH and KH.

You did that so you could measure or calculate the size of <JHK. There are 5 such central angles in a pentagon. If you drew a little circle with H as the center and you went around the circle once, you would have traveled 360 degrees. So <JHK = 360/5 = 72. Make sure you understand that before you read on.

Ok here's the trick. 144 = 2*72. That means that when you rotate the pentagon, you rotate it through Two central angles.

What will happen is that Point J will wind up at Point L and Point K will sit where N is right now. All the points not mentioned will do the same thing. They will move two points clockwise.
