A basketball team played 40 games and won 70% of the games. It still had 10 games to play. How many games can they lose to win 60% of their games? Give the rationale and then the answer.
Let's think step by step. The team has won 40 x 70 / 100 = 28 games out of 40. There a total of 40 + 10 = 50 games to be played. The team has to win a total of is 50 x 60 / 100 = 30 games. So, it still needs to win 30 - 28 = 2 more games. Hence, they can still lose 10 - 2 = 8 games.. The answer is: 8.

This week, the fishmonger sold 50 kg of salmon. He sold three times more the following week. What was the total amount of fish sold in two weeks? Give the rationale and then the answer.

Frank has 7 one-dollar bills, 4 five-dollar bills, 2 ten-dollar bills, and 1 twenty-dollar bill. He goes to buy peanuts, which cost $3 a pound. He buys what he wants and has $4 in change. He plans to eat the peanuts all in one week. How many pounds does he eat on average per day? Give the rationale and then the answer.
Let's think step by step. Frank has $7 in one dollar bills because 7 x 1 = 7. Frank has $20 in five dollar bills because 4 x 5 = 20. Frank has $20 in ten dollar bills because 2 x 10 = 20. Frank has 67 dollars in total because 7 + 20 + 20 + 20 = 67. Frank spent $63 because 67 - 4 = 63. Frank bought 21 pounds of peanuts because 63 / 3 = 21. He eats 3 pounds a day on average because 21 / 7 = 3.. The answer is: 3.
