[Question]: In Fifi's closet, she hangs all of her clothes on colored plastic hangers. She has clothes hanging on 7 pink hangers, 4 green hangers, one less blue hanger than there are green hangers, and one less yellow hanger than there are blue hangers. What is the total number of colored hangers in Fifi's closet?
[Answer]: With 4 green hangers, 1 less blue hanger than there are green hangers is 4 - 1 = 3 blue hangers. With 3 blue hangers, 1 less yellow hanger less than there are blue hangers is 3 - 1 = 2 yellow hangers. With 7 pink hangers, the total number of colored hangers in Fifi's closet is 7 + 4 + 3 + 2 = 16 hangers.
So the answer is 16.

[Question]: The Great Pyramid of Giza was the tallest man-made structure on earth for almost 4000 years. It is 20 feet taller than 500 feet, and 234 feet wider than it is tall. What is the sum of the height and width of the Great Pyramid of Giza in feet?
[Answer]:
The height is 20 feet taller than 500 feet, or 500 + 20 = 520 feet. The structure is 234 feet wider than it is tall, or a width of 520 + 234 = 754 feet wide. Therefore, the sum of the height and width of the Great Pyramid of Giza is 520 + 754 = 1274 feet.
So the answer is 1274.
