Question: Vann is a veterinarian. Today he is going to be doing dental cleanings only. Dogs have 42 teeth, cats have 30 teeth and pigs have 28 teeth. If he is to do 5 dogs, 10 cats and 7 pigs, how many total teeth will Vann clean today?
Answer: First let's find the number for each animal separately, 42 teeth per dog * 5 dogs = 210 teeth for dogs. Then cats total will be 30 teeth per cat * 10 cats = 300 teeth in total for cats. Finally, the number for pigs is 28 teeth per pig * 7 pigs = 196 teeth in total for pigs. So the total in all is 210 teeth + 300 teeth + 196 teeth = 706 teeth in total. The answer is 706.

Question: Alina and her best friend Lucia like to chat a lot. On a particular day, Alina sent 20 fewer messages than her friend Lucia, who sent 120 messages. The next day, Lucia sent 1/3 of the messages she sent the previous day, while Alina doubled the messages she sent on the first day. If they sent the same number of messages on the third day as the first day, what is the total number of messages they sent in those three days?
Answer: On the first day, Alina sent 120 - 20 = 100 messages. The total number for the first day is 100 + 120 = 220 messages. On the second day, Lucia sent 1 / 3 * 120 = 40 messages. Alina sent 100 * 2 = 200 messages on the second day. The total for the second day is 40 + 200 = 240 messages. For the three days, they sent 220 + 220 + 240 = 680 messages. The answer is 680.

Question: Samantha bought a crate of 30 eggs for $5. If she decides to sell each egg for 20 cents, how many eggs will she have left by the time she recovers her capital from the sales?
Answer: There are 100 cents in each $1 so $5 gives 5 * 100 cents = 500 cents. To recover her capital of 500 cents from a selling price of 20 cents per egg she has to sell 500 / 20 = 25 eggs. There were 30 eggs in the crate to start with so she will have 30 - 25 = 5 eggs left. The answer is 5.

Question: Lilibeth and her friends go strawberry picking. Lilibeth fills 6 baskets where each basket holds 50 strawberries. If three of Lilibeth's friends pick the same amount as her, how many strawberries do Lilibeth and her friends pick in all?
Answer:
Lilibeth picks 6 x 50 = 300 strawberries. There are 1 + 3 = 4 of them who are picking strawberries. Therefore, they pick a total of 300 x 4 = 1200 strawberries. The answer is 1200.
