[Question]: Stephen ordered 2 large pizzas, both cut into 12 slices. He ate 25% of the pizza. His friend Pete ate 50% of the remaining pizza. How many slices are left over?
[Answer]: He ordered 2 pizzas, each cut into 12 slices so that's 2 * 12 = 24 slices. Stephen ate 25% of the pizza so he ate .25 * 24 = 6 slices. That leaves 24 - 6 = 18 slices. 18 slices are left and Pete eats 50% of 18 slices so he eats 18 * .50 = 9 slices. If there were 18 slices and Pete ate 9 slices then there are 18 - 9 = 9 slices left over.
So the answer is 9.

[Question]: Rockefeller Army Base has 3000 more than twice as many guns as Grenada Army Base, 400 less than thrice as many war tractors as Grenada Army Base, and 30 times as many soldier uniforms as Grenada Army Base reserved for its national protection. How many total war supplies does Rockefeller have if Grenada's war supplies are equally divided among the 6000 war supplies they have in total?
[Answer]: For each component, Grenada Army Base has 6000 / 3 = 2000 each of guns, war tractors, and soldier uniforms. Rockefeller Army Base has 3000 + 2 * 2000 = 7000 guns. Rockefeller Army Base has 3 * 2000 - 400 = 5600 war tractors. Rockefeller Army Base has 30 * 2000 = 60000 soldier uniforms. The total war supplies Rockefeller Army Base has reserved are 60000 + 5600 + 7000 = 72600 war supplies for its national protection.
So the answer is 72600.

[Question]: Ron is part of a book club that allows each member to take a turn picking a new book every week. The club is made up of three couples and five single people along with Ron and his wife. How many times a year does Ron get to pick a new book?
[Answer]:
There are 3 couples in the club, so there are 3 * 2 = 6 people in couples in the club. Along with the singles and Ron and his wife, there are 6 + 5 + 2 = 13 people in the book club. There are 52 weeks in a year, so Ron gets to pick a new book 52 / 13 = 4 times a year.
So the answer is 4.
