Clayton plays basketball on a team. He has played three games so far. In the first game, he scored 10 points. In the second game, he scored 14 points. In the third game, he scored 6 points. In the fourth game, he scored the average of his points from the first three games. How many total points did Clayton score during the first four games? Give the rationale and then the answer.
Let's think step by step. During the first three games Clayton scored 10 points + 14 + 6 = 30 points. The average for Clayton's first three games is 30 points / 3 = 10 points per game. For the first four games, Clayton scored 30 points + 10 points = 40 points.. The answer is: 40.

On Mary's birthday, her brother surprised her with $100. She spent a quarter of it on a new video game and then used a fifth of what was left on swimming goggles. How much money did she have left? Give the rationale and then the answer.
Let's think step by step. Mary spent 100 / 4 = 25 dollars on a new video game. So, after the video game purchase, Mary was left with 100 - 25 = 75 dollars. Mary then bought swimming goggles for 75 / 5 = 15 dollars. Mary had 75 - 15 = 60 dollars left.. The answer is: 60.
