David and Karen have a goal to read 10,000 pages together by the end of the summer.

David reads 80 pages every day.

Karen reads 25% more pages every day than David reads.

David and Karen agree that the model 180d = 10,000 will tell them how many days it will take them to read 10,000 pages, together, by the end of the summer.

They invite Rick to read with them to get to their goal faster. Rick reads 35% fewer pages per day than Karen.

Marco says that the interior angles of a triangle add up to 180\degree. He claims that the interior angles of a hexagon must add up to 360\degree because a hexagon has twice as many vertices as a triangle and can be divided into two triangles. Therefore, its interior angles must sum to twice the value of those of a triangle.

Which statement, if any, explains Marco's error?
