Q: Mario's salary increased by 40% to $4000 this year. Bob's salary from last year was equal to three times Mario's salary this year. If Bob's current salary is 20% more than his salary last year, what is his current salary?
A: Last year, Bob's salary was equal to three times Mario's salary this year, meaning Bob was earning 3 * $4000 = $12000. If Bob's salary increased by 20% this year, he is earning 20 / 100 * $12000 = $2400 more. Bob's total salary this year is $12000 + $2400 = $14400. The answer is 14400.
Question: Martha has 20 apples. She decided to split them among her friends. Jane got 5 apples from her, and James got 2 more than Jane. How many more apples would Martha need to give away to be left with only 4 of them?
Answer: Martha gave James 5 + 2 = 7 apples. So Martha was left with 20 - 5 - 7 = 8 apples. To be left with only 4 apples, Martha would need to give away 8 - 4 = 4 more apples. The answer is 4.

Q: While practising for his upcoming math exams, Hayes realised that the area of a circle he had just solved was equal to the perimeter of a square he had solved in the previous problem. If the area of the circle was 100, what's the length of one side of the square?
A: Let's say the side of a square is s.To get the perimeter of a square, you add all the sides, which is s + s + s + s = 100. Therefore, 4s = 100. Therefore one side of the square is s = 100 / 4 = 25. The answer is 25.
Question: A soccer team has 24 players. They have scored 150 goals on the season. There have been 15 games played. 1/3 of the players have averaged 1 goal each per game. How many total goals have the other players scored?
Answer: 8 players have averaged 1 goal a game because 24 x (1 / 3) = 8. These players average a total of 8 goals a game because 8 x 1 = 8. These players have scored 120 goals because 8 x 15 = 120. The remaining players have scored 30 total goals because 150 - 120 = 30. The answer is 30.
