Question: A farmer plants his vegetables in neat rows. He has 64 bean seedlings and plants 8 seedlings in a row. He also has 84 pumpkin seeds and plants 7 seeds in a row. Recently, he planted 48 radishes with 6 radishes in a row. If the farmer plants two rows per plant bed, how many plant beds did he have for all his plants?
Answer: There are 64 / 8 = 8 rows of bean seedlings. There are 84 / 7 = 12 rows of pumpkin seedlings. There are 48 / 6 = 8 rows of radishes. Thus, there are a total of 8 + 12 + 8 = 28 rows of vegetables. Therefore, the farmer had 28 / 2 = 14 plant beds. The answer is 14.
[Question]Mindy has 7 less than 9 times as many emails waiting for her as phone messages. If she has a total of 93 emails and phone messages combined, how many emails does she have?
[Answer]Let e be the number of emails Mindy has and m be the number of phone messages? We know that e + m = 93 and e = 9m - 7. Substituting the second equation into the first equation, we get 9m - 7 + m = 93. Combining like terms, we get 10m - 7 = 93. Adding 7 to both sides of the equation, we get 10m = 100. Dividing both sides by 10, we get m = 10. Substituting this value back into the equation e = 9m - 7, we get e = 9 * 10 - 7 = 90 - 7 = 83. The answer is 83.

Q: Brittney can chop 15 onions in 5 minutes. Carl can chop 20 onions within that same time. How many more onions can Carl chop in 30 minutes than Brittney?
A:
Brittney can chop 15 / 5 = 3 onions in one minute. Carl can chop 20 / 5 = 4 onions in one minute. Brittney can chop 3 x 30 = 90 onions in 30 minutes. Carl can chop 4 x 30 = 120 onions in 30 minutes. Carl can chop 120 - 90 = 30 more onions than Brittney in 30 minutes. The answer is 30.
