One week later, kiosk a reduced the price by 15%, and another week later, kiosk B increased the price by 30%. Kiosk B only raised the price by 15% two weeks later. Which one of kiosks A and B sold more in two weeks? 2. Our body needs to take in 2500 ml water every day. 48% of the water is from food, and the rest is from drinking water. How much water does the human body get from drinking water every day?

What's the price in two weeks
240 × (1-15%) × (1 + 30%) = 265.2 yuan
What's the price of B
240 × (1 + 15%) = 276 yuan
Therefore, the price of B is high
2. Our body needs to take in 2500 ml water every day. 48% of the water is from food, and the rest is from drinking water. How much water does the human body get from drinking water every day?
2500 × (1-48%) = 1300 ml

Solve a quaternion equation of first degree Some AI can't solve it
For you knowledgeable relatives, it should be very simple
5x+4y+3z+2w=1496
4x+2y+6z+3w=1175
3x+y+7z+5w=958
2x+3y+5z+w=861

Because 5x + 4Y + 3Z + 2W = 1496
4x+2y+6z+3w=1175
3x+y+7z+5w=958
2x+3y+5z+w=861
So x + 2Y + (- 3Z) + (- W) = 321
2x+3y-4z-3w=538
x+y-z-2w=217
2z+4w=644
x+y+z+2W=861
That's it

1. If | x + 1 | and | 2Y + 3 | are opposite numbers, then X=_____ ,y=_____ ,x+y=_____
2. If b > 0 and a + B < 0, the following conclusions are wrong_____
A.a＜0 B.a-b＜0 C.a+|b|＞0 D.|a|+b＞0
3. The sum of three numbers - 12, - 2, + 7 is smaller than the sum of their absolute values_____
4. If a is a rational number, then the sum of - A and | a | is
A. It can be negative B. It can't be negative C. It can only be positive D. It can only be 0
5. If a and B are different signs, a + b > 0 and a < 0, then the relationship between | a | and | B | is positive_____
A.|a|＞|b| B.|a|＜|b| C|a|≥|b| D.|a|≤|b|
