As seen from the figure:
Group 1: It consists of three closed figures each having six sides. So these are all hexagons.
Group 2: It consists of three closed figures each having four sides.
All four are quadrilaterals.
So we can say that group 1 consists of hexagons and group two consists of quadrilaterals.
$480 is the price after the discount was added. We can then assume that $480 is 3/4 the price of the original item. To find 1/4, we simply divide by 3, which equals $160. since $160 is one quarter of the price, the original price was $640.
