Robin has 130 stickers. 10 stickers fill a page. How many pages of 10 stickers does she need to have 200 stickers in all? Robin needs pages of stickers.

She needs 7 extra pages to have 200 stickers.

y=10x + 130

10x + 130=200

10x 130 - 130 = 200 - 130 (Subtract both sides by 130)

10x = 70

x= 70/10 (Divide 70 by 10)

x=7
