Question: Danny made chocolate cookies for his class and made sure each cookie had exactly 7 chips. He made 4 dozen in total. If the class eats half the cookies, how many chips are left uneaten?
Answer: There are 48 cookies because 12 x 4 = 48. There are 24 cookies left because 48 / 2 = 24. There are 168 chips left because 24 x 7 = 168. The answer is 168.

Q: Paul eats a lot when he studies. He loves sandwiches and eats them at the same rate every three days. He eats 2 sandwiches the first day, then doubles that number of sandwiches for the second day. On the third day, he doubles the number of sandwiches he ate on the second day. How many sandwiches would Paul eat if he studied 6 days in a row?
A: Paul doubles the amount that he ate on the second day, so eats 2 x 2 = 4 sandwiches. For the third day, he doubles the number of sandwiches he ate on the second day, so eats 2 x 2 x 2 = 8 sandwiches. To get the total amount of sandwiches he ate over three days it's necessary to add up the amount he ate each day: 2 + 4 + 8 = 14 sandwiches. Since he eats 14 sandwiches every 3 days, then in 6 days he would eat 14 x 2 = 28 sandwiches in total. The answer is 28.
Question: Kim is an office manager. Every morning she spends 5 minutes making coffee, 2 minutes per employee getting a status update, and 3 minutes per employee updating payroll records. If there are 9 employees in the office, how long does Kim's morning routine take?
Answer: First find how many minutes Kim spends on each employee: 2 minutes / employee + 3 minutes / employee = 5 minutes / employee. Then multiply that time by the number of employees to find the total time spent on status and payroll updates: 5 minutes / employee * 9 employees = 45 minutes. Finally, add that time to the time spent making coffee to find the total time: 45 minutes + 5 minutes = 50 minutes. The answer is 50.
Q: Phyllis has two gardens. In the first garden, she has 20 plants and 10% are tomato plants. In the second garden, she has 15 plants and 1/3 of these plants are tomato plants. What percentage of all the plants in her two gardens are tomato plants?
A:
The first garden has 2 tomato plants because 20 x .1 = 2. The second garden has 5 tomato plants because 15 x (1 / 3) = 5. She has 7 tomato plants in total because 2 + 5 = 7. She has 35 plants in total because 20 + 15 = 35. The proportion of tomato plants is .2 because 7 / 35 = .2. The percentage of tomato plants is 20 because .2 x 100 = 20. The answer is 20.
