Question: My dog was born when I was 15 years old. Two years from now, my dog will turn 4 years old. How old am I now?
Answer: Step-by-step reasoning process: In 2 years, my dog will be 4 years old, so my dog is 4 - 2 = 2 years old now. So I am 15 + 2 = 17 years old now.
So the answer is 17.

Question: Lucille made an agreement with her mom that she would earn six cents for every weed she pulled in her mom's garden. There are eleven weeds in the flower bed, fourteen in the vegetable patch, and thirty-two in the grass around the fruit trees. Lucille weeded the flower bed, the vegetable patch, and half the grass before she took a break. She bought a soda for 99 cents on her break with some of her earnings. How many cents does Lucille have left?
Answer: Step-by-step reasoning process: Lucille weeded half the grass, so she pulled 32 / 2 = 16 weeds around the fruit frees. She pulled 11 + 14 + 16 = 41 weeds before her break. From that, she earned 41 * 6 = 246 cents. After buying her soda, Lucille has 246 - 99 = 147 cents left.
So the answer is 147.

Question: Johnny is an engineer designing a bridge. The roadway deck for the top of the bridge needs 1600 tons of concrete to construct. The two bridge anchors need equal amounts of concrete, but only one has been built so far, using 700 tons of concrete. Johnny had to calculate how many tons of concrete the supporting pillars underneath the bridge would need, and he found that the total amount of concrete in the entire bridge will be 4800 tons. How much concrete did Johnny find he needs for the supporting pillars?
Answer: Step-by-step reasoning process: The bridge anchors will take 700 * 2 = 1400 tons of concrete. The roadway deck and bridge anchors need 1600 + 1400 = 3000 tons of concrete. Thus, Johnny found the supporting pillars need 4800 - 3000 = 1800 tons of concrete.
So the answer is 1800.

Question: Jake is from a conservative household so during lunch at school one day, he gave one-quarter of his feeding allowance to a hungry friend. If candies cost 20 cents apiece and Jake's feeding allowance is $4, how many candies can his friend purchase with the money Jake gave to him?
Answer:
Step-by-step reasoning process: One quarter of $4 is (1 / 4) * $4 = $1. $1 is equivalent to 100 cents. 20 cents will buy 1 candy so 100 cents will buy 100 / 20 = 5 candies.
So the answer is 5.
