Answer the following question.
Fabian is shopping at a nearby supermarket. He wants to buy 5 kilograms of apples, 3 packs of sugar, and 500 grams of walnuts. One kilogram of apples costs $2, and one kilogram of walnuts costs $6. One pack of sugar is $1 cheaper than one kilogram of apples. How much Fabian needs to pay for the items he wants to buy?
Step-by-step reasoning process: The apples cost Fabian 5 kg * $2 / kg = $10. For the walnuts Fabian needs to pay 0.5 kg * $6 = $3. One pack of sugar costs $2 - $1 = $1. So Fabian will pay $1 / pack * 3 = $3 for sugar. In total, Fabian needs to pay $10 + $3 + $3 = $16.
The answer is 16.

Answer the following question.
Mike decides to develop a plot of land. He bought 200 acres for $70 per acre. After development, he sold half of the acreage for $200 per acre. How much profit did he make?
Step-by-step reasoning process: He bought the land for 200 * 70 = $14000. He sold 200 / 2 = 100 acres. He got 100 * 200 = $20,000 from selling this. So he made a profit of 20,000 - 14,000 = $6,000.
The answer is 6000.

Answer the following question.
Claudia offers art classes to kids and charges $10.00 for her one-hour class. If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make?
Step-by-step reasoning process: Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20 / 2 = 10 kids. She has 20 kids on Saturday and 10 kids on Sunday for a total of 20 + 10 = 30 kids. She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10 * 30 = $300.00.
The answer is 300.

Cori is 3 years old today. In 5 years, she will be one-third the age of her aunt. How old is her aunt today?

The answer is 19.
