Question: Teddy has 7 dogs and 8 cats. Ben has 9 more dogs than Teddy, and Dave has 13 more cats and 5 less dogs than Teddy. How many pets do all of them have combined?
Answer: Teddy has 7 + 8 = 15 pets in total. Ben has 9 + 7 = 16 dogs, which means he has 16 pets in total. Dave has 13 + 8 = 21 cats. Dave has 7 - 5 = 2 dogs. Dave has 21 + 2 = 23 pets in total. Combined, they have 15 + 16 + 23 = 54 pets in total. The answer is 54.

Question: Ann, Becky, and Julia are working at a pharmacy, every day for 8 hours. Each of them is providing service to 7 customers per hour. One day Julia had to finish her work earlier, so she was working only for 6 hours. How many customers did all three of these women serve that day in total?
Answer: Ann and Becky have worked for 8 hours each, so both of them worked for 2 people * 8 hours / person = 16 hours. All three of them, including Julia, were working for 16 hours + 6 hours = 22 hours. So in total, they all have served 7 customers / hour * 22 hours = 154 customers in one day. The answer is 154.

Question: In a conference room, 40 chairs with a capacity of 2 people each were arranged in rows in preparation for the board meeting of a company, whose number of members was the same as the chairs' capacity. If 2/5 of the chairs were not occupied, and the rest each had two people, calculate the number of board members who did attend the meeting.
Answer: The total capacity of the 40 chairs was 40 * 2 = 80 people. If 2 / 5 of the chairs were unoccupied, 2 / 5 * 80 = 32 people missed the board meeting since the number of members was the same as the chair's capacity. The number of board members who attended the meeting was 80 - 32 = 48. The answer is 48.

Question: Aitana and Jayda went to Silverlake Flea market to buy some handmade crafts. Aitana spent 2/5 times more money than Jayda at the market. If Jayda spent $400, calculate the total amount of money they spent together.
Answer:
If Jayda spent $400 at the market, Aitana spent 2 / 5 * 400 = $160 more on handmade crafts. Since Aitana spent $160 more than Jayda at the market, she spent $400 + $160 = $560. The total amount of money they spent together is $400 + $560 = $960. The answer is 960.
