Q: Of the 100 soccer balls that Nova went to inflate, 40 percent had holes in them and could not inflate, while 20% of the remaining balls were overinflated and exploded. How many balls were inflated successfully and could be used?
A: If 40% of the balls had holes in them and could not inflate, their number was 40 / 100 * 100 = 40. The remaining balls that Nova could inflate were 100 - 40 = 60. While inflating, 20% of the good soccer balls were overinflated and exploded up, a total of 20 / 100 * 60 = 12. The number of soccer balls that inflated successfully and could be used is 60 - 12 = 48. The answer is 48.
Question: Maryann spends seven times as long doing accounting as calling clients. If she worked 560 minutes today, how many minutes did she spend calling clients?
Answer: Let a be the amount of time Maryann spends doing accounting and c be the amount of time she spends calling clients: We know that a + c = 560 and a = 7c. Substituting the second equation into the first equation, we get 7c + c = 560. Combining like terms, we get 8c = 560. Dividing both sides by 8, we get c = 70. The answer is 70.
[Question]Each year Dani gets 4 pairs of two pants each as pay winning the best Amazon buyer of the season. If he initially had 50 pants, calculate the number of pants he'll have in 5 years.
[Answer]Since he receives four pairs of pants every year, and a pair has two pants, he gets 4 * 2 = 8 pants every year. After five years, the total number of pants he'll receive is 5 * 8 = 40 pants. If he initially had 50 pants, he'll have a total of 50 + 40 = 90 pants in five years. The answer is 90.
[Question]Mr. Salazar had seven dozen oranges. He reserved 1/4 of it for his friend and was able to sell 3/7 of the remaining yesterday. Today, he saw four rotten oranges. How many oranges are left to be sold today?
[Answer]
Mr. Salazar had 7 x 12 = 84 oranges. He reserved 84 x 1 / 4 = 21 oranges for his friend. Ha had 84 - 21 = 63 oranges to be sold yesterday. But only 63 x 3 / 7 = 27 oranges were sold yesterday. So, he had 63 - 27 = 36 oranges left. Since four oranges are rotten, then only 36 - 4 = 32 oranges are left to be sold today. The answer is 32.
