Q: A country plans to reduce its carbon emissions by 10% each year. If the current emissions are 500 tons, what will be the emissions after 2 years?

Solution: Emissions after 1 year = 500 * (1 - 0.10) = 500 * 0.90 = 450 tons. After 2 years = 450 * 0.90 = 405 tons.

Steps: 8

Step 1: Start with the current emissions, which are 500 tons.
Step 2: Calculate the emissions after 1 year by reducing 10% of 500 tons.
Step 3: To find 10% of 500, multiply 500 by 0.10, which equals 50 tons.
Step 4: Subtract the 10% (50 tons) from the current emissions (500 tons). So, 500 - 50 = 450 tons.
Step 5: Now, take the emissions after 1 year (450 tons) and calculate the emissions after 2 years by reducing another 10%.
Step 6: Calculate 10% of 450 tons by multiplying 450 by 0.10, which equals 45 tons.
Step 7: Subtract the 10% (45 tons) from the emissions after 1 year (450 tons). So, 450 - 45 = 405 tons.
Step 8: The emissions after 2 years will be 405 tons.
