How many cookies does Celinda bake? ** Celinda bakes 30 cookies * 2 = <<30*2=60>>60 cookies.
How many cookies does Celinda and Greta bake? ** So in total, Celinda and Greta bakes a total of 30 + 60 = <<30+60=90>>90 cookies.
How many cookies are in the box? ** After eating some of the cookies, they have 90 baked cookies – 10 eaten cookies = <<90-10=80>>80 cookies in the box.
