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?
Let's think: 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.

John is holding a poker night with his friends and is getting the decks of cards ready before his friends show up. After losing so many cards from various decks, John thinks he needs to count exactly how many cards he has to make sure he has enough full decks for the night. Each deck of cards should hold 52 cards. He finds 3 half-full decks of cards and 3 full decks of cards. As he is arranging them, he realizes that the quality of a lot of the cards is quite poor and decides to throw 34 of the cards in the trash. How many cards does John now have?
Let's think: In the full decks, John has a total of 52 cards in a full deck of cards * 3 full decks of cards = 156 cards. A half - full deck of cards contains 52 cards in a full deck of cards / 2 = 26 cards. So from the half - full decks, John has a total of 26 cards * 3 half - full decks = 78 cards. This is a total of 156 cards from full decks + 78 cards from half - full decks = 234 cards. After throwing some in the trash, he now holds a total of 234 cards - 34 trashed cards = 200 cards.. The answer is: 200.

Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether?
Let's think: The total ratio for the number of cats and dogs that Heloise has is 10 + 17 = 27. From the ratios, the fraction representing the number of dogs is 10 / 27, and this represents 10 / 27 * 189 = 70 dogs. If Heloise gives 10 of her dogs to Janet, she remains with 70 - 10 = 60 dogs.. The answer is: 60.

John buys 3 t-shirts that cost $20 each. He also buys $50 in pants. How much does he spend?
Let's think:
He spends 20 * 3 = $60 on t - shirts. So he spends 60 + 50 = $110 in total.. The answer is: 110.
