75,000, how much tax must that citizen pay to each of the two countries?

21. A giant pumpkin is 90% water and weighs 250 pounds. The pumpkin is placed on display as the largest pumpkin of the year at the LA county fair. During the week-long fair, the pumpkin loses water from being outside in the heat. At the end of the week, the pumpkin is only 80% water. How much does the pumpkin weigh at the end of the week?

To calculate the amount of tax a citizen must pay to each of the two countries, we need more information. Tax rates, income brackets, and tax laws may vary between countries. Without these details, it is not possible to provide an accurate answer. I recommend referring to the tax regulations and guidelines of both countries and consulting with a tax professional to accurately determine the tax liability.

Regarding the weight of the pumpkin at the end of the week, let's calculate it:

Given:
- The giant pumpkin originally weighs 250 pounds.
- The pumpkin is initially 90% water.
- At the end of the week, the pumpkin is only 80% water.

We can find the weight of water in the pumpkin at the end of the week and subtract it from the original weight to determine the final weight.

Step 1: Calculate the weight of water in the pumpkin initially.
Weight of water = (90/100) * 250 pounds = 0.9 * 250 pounds = 225 pounds

Step 2: Calculate the weight of water in the pumpkin at the end of the week.
Weight of water at the end of the week = (80/100) * Weight of water initially = (80/100) * 225 pounds = 0.8 * 225 pounds = 180 pounds

Step 3: Calculate the final weight of the pumpkin.
Final weight = Initial weight - Weight of water at the end of the week = 250 pounds - 180 pounds = 70 pounds

Therefore, the pumpkin weighs 70 pounds at the end of the week.
