Question: Yuri has been adopting puppies for a month now. The first week he adopted 20 puppies, the second week 2/5 times as many puppies as the first week, the third week twice the number of puppies he adopted in the second week, and the fourth week ten more puppies than he adopted on the first week. How many puppies does Yuri have now?
Answer with step-by-step thinking: The number of adopted puppies in the second week is 2 / 5 * 20 puppies = 8 puppies. In the third week, Yuri adopted 2 * 8 puppies = 16 puppies. In the fourth week Yuri adopted ten more puppies than the third week, which totals 10 puppies + 20 puppies = 30 puppies. The total number of puppies in the four weeks is 30 puppies + 16 puppies + 8 puppies + 20 puppies = 74 puppies.
So the answer is 74.

Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches.
So the answer is 82.
