Answer this question:A dog runs through a field and is joined by a group of 4 cats. 2 rabbits join each cat and 3 hares join each rabbit. How many animals are running through the field?
A pair of rabbits join each cat so there must be 4 cats * 2 rabbits / cat = 8 rabbits. As 3 hares join each rabbit, there must be 8 rabbits * 3 hares / rabbit = 24 hares. Counting all the animals shows there are 1 dog + 4 cats + 8 rabbits + 24 hares = 37 animals running through the field.

Answer this question:Jackie loves to climb trees. She climbed a 1000 foot tall tree. Then she climbed 2 trees that were half as tall as the first tree. She finished by climbing a tree that was 200 feet taller than her first tree. What was the average height of the trees that Jackie climbed?
Jackie climbed 2 trees that were 1 / 2 * 1000 feet = 500 feet tall each. Jackie climbed a final tree that was 1000 + 200 feet = 1200 feet. In total, the 4 trees Jackie climbed were 1000 feet + 500 feet + 500 feet + 1200 feet = 3200 feet. The average height tree that Jackie climbed was 3200 feet / 4 trees = 800 feet tall.
The answer is 800.

Answer this question:There is a 5,200 sq. ft. house and a 7,300 sq. ft. house next to each other. The smaller house is being expanded. If the new total square footage of both houses is 16,000 sq. ft., how much is the smaller house being expanded by, in sq. ft.?
Originally, the houses are 7300 + 5200 = 12500 sq. ft. in total. The smaller house will be expanded by 16000 - 12500 = 3500 sq. ft.
The answer is 3500.
