[Question]Ben has four boxes with ten basketball cards in each box. His mother gave him five boxes with eight baseball cards. If he gives 58 cards to his classmates, how many cards does he has left?
[Answer]Ben has 4 x 10 = 40 basketball cards. His mother gave him 5 x 8 = 40 baseball cards. Thus, Ben has 40 + 40 = 80 cards in all. Therefore, Ben has 80 - 58 = 22 cards left. The answer is 22.
Q: At a gathering, it was reported that 26 people took wine, 22 people took soda, and 17 people took both drinks. If each person could have taken one or more drinks regardless of what was reported, how many people altogether were at the gathering?
A: The number of people who took only wine is the difference between the number of people who took wine and those who took wine and soda which is 26 - 17 = 9 people. In the same manner, the number of people who took only soda is 22 - 17 = 5 people. Therefore the total number present is the sum of those who took wine only, those who took soda only and those who took both which is 9 + 5 + 17 = 31 people. The answer is 31.
Question: Ken can do 20 sit-ups without stopping. Nathan can do twice as many, and Bob can do half the number of Ken and Nathan's combined sit-ups. How many more sit-ups can Bob do compared to Ken?
Answer:
