James streams on twitch. He had 150 subscribers and then someone gifted 50 subscribers. If he gets $9 a month per subscriber how much money does he make a month?
Let's think: He now has 150 + 50 = 200 subscribers. So he makes 200 * 9 = $1800 a month.. The answer is: 1800.

Wilson decides to go sledding on some nearby hills. On the 2 tall hills, he sleds down them 4 times each and on the 3 small hills, he sled down them half as often as he sleds down the tall hills. How many times did he sled down the hills?
Let's think: On the tall hills, he sleds down 2 tall hills * 4 times per tall hill = 8 times. He sleds down the small hills half as often so he sleds down each hill 4 times per tall hill / 2 = 2 times per small hill. On the small hills, he sleds down 3 small hills * 2 times per small hill = 6 times. So in total, Wilson sled down the hills 8 times on tall hills + 6 times on small hills = 14 times.. The answer is: 14.

In a 100-item exam, Lowella got 35% of the questions correctly. Pamela got 20% more correct answers than Lowella and Mandy got twice Pamela's score. What is Mandy’s score?
Let's think: Lowella got 100 x 35 / 100 = 35 correct answers. Pamela got 35 x 20 / 100 = 7 more correct answers than Lowella. So, Pamela got 35 + 7 = 42 correct answers. Thus, Mandy got 42 x 2 = 84 correct answers.. The answer is: 84.

Cara is at her family reunion, where she discovers that she is 20 years younger than her mom. Her mom is 15 years younger than Cara's Grandmother. If Cara's grandmother is 75, how old is Cara?
