[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?
[Answer]: 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.
So the answer is 16.

[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?
[Answer]: 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.
So the answer is 300.

[Question]: It will take Richard and Sarah 3 years to save enough for a down payment on a house at their current rates. If the house's downpayment is $108000, calculate the amount each person saves per month if they share the monthly savings.
[Answer]:
If they are to save every month for three years to reach the target amount, and each year has 12 months, they'll save for 12 * 3 = 36 months. If the house's downpayment is $108000, the total amount they both save per month is $108000 / 36 = $3000 every month. Since they share the monthly savings, each person will pay $3000 / 2 =  = $1500.
So the answer is 1500.
