We have a question: Joseph had socks of many different colors. His dresser drawer was filled to overflowing with red, blue, black, and white socks. Uncertain of how many pairs he had of each color, he began to sort his socks. He discovered that he had three more pairs of blue socks than he had pairs of black socks. He had one less pair of red socks than he had pairs of white socks. He had twice as many blue socks as he had of red socks. And he counted a total of 6 red socks. What is the total number of Joseph's socks?
And an answer: 28
So how you got the answer?
Starting with 6 red socks, twice the number of blue socks as red meant Joseph had 2 * 6 = 12 blue socks. With one less pair of red socks than white socks, this meant 2 fewer red socks than white, for a total of 6 - 2 = 4 white socks. Also, 12 blue socks = 6 pairs of blue socks. With three more pairs of blue socks than pairs of black socks, this means he had 6 - 3 = 3 pairs of black socks. And three pairs of black socks corresponds to 3 * 2 = 6 black socks. Thus, in total, he had 6 + 12 + 4 + 6 = 28 socks.

We have a question: Margo donated $4300 to Jayden's fundraising campaign. If Julie donated $4700 to Jayden's campaign, What's half the difference in the amount they contributed?
And an answer: 200
So how you got the answer?
If Julie donated $4700 to Jayden's campaign, and Margo donated $4300, the difference in their contribution is $4700 - $4300 = $400. Half the difference in the amount they contributed is 1 / 2 * $400 = $200.

We have a question: Jack went to a supermarket with $100 and bought 4 bottles of water. Then his mother called him and asked him to buy twice as many bottles as he already bought. Each bottle cost $2. Finally, he also bought half a pound of cheese and 1 pound of cheese costs $10. How much money does Jack have remaining?
And an answer: 71
So how you got the answer?
Jack's mother asked him to buy 2 * 4 = 8 bottles of water. Thus Jack bought 4 + 8 = 12 bottles of water in total. Altogether, the bottles of water cost 12 * $2 = $24. The cheese cost 1 / 2 * $10 = $5. So Jack spent $24 + $5 = $29 on water and cheese. Since he started with $100, he now has $100 - $29 = $71 left.
