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: Step-by-step reasoning process: 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.
So the answer is 706.

Question: If Beth had $35 more, she would have $105. If Jan had $10 less, he would have the same money as Beth has. How much money do Beth and Jan have altogether?
Answer: Step-by-step reasoning process: Beth has $105 - $35 = $70. Jan has $70 + $10 = $80. So, Beth and Jan have $70 + $80 = $150 altogether.
So the answer is 150.

Question: Karen’s work tote bag is twice the weight of her husband Kevin’s briefcase when the briefcase is empty. When Kevin puts his laptop and work papers in his briefcase, it is twice the weight of Karen’s tote. Kevin’s work papers are a sixth of the weight of the contents of his full briefcase. If Karen’s tote weighs 8 pounds, how many more pounds does Kevin’s laptop weigh than Karen’s tote?
Answer: Step-by-step reasoning process: Kevin’s full briefcase is 2 * 8 = 16 pounds. His empty briefcase is 8 / 2 = 4 pounds. The contents of his briefcase weigh 16 - 4 = 12 pounds. His work papers weigh 12 / 6 = 2 pounds. Thus, his laptop weighs 12 - 2 = 10 pounds. Therefore, Kevin’s laptop weighs 10 - 8 = 2 pounds more than Karen’s tote.
So the answer is 2.

Question: Three-quarters of the oil from a 4000-liter tank (that was initially full) was poured into a 20000-liter capacity tanker that already had 3000 liters of oil. How many more liters of oil would be needed to make the large tanker half-full?
Answer:
Step-by-step reasoning process: Three - quarters of oil from the initially full 4000 - liter tank would be 4000 * (3 / 4) = 3000 liters. In addition to the 3000 liters that were already in the large tanker, there are 3000 + 3000 = 6000 liters in it now. The tanker would be filled to half capacity by (1 / 2) * 20000 = 10000 liters of oil. There are 10000 - 6000 = 4000 liters left to reach half capacity.
So the answer is 4000.
