Questions & Step-by-Step Solutions
A country signed a treaty that will reduce its carbon emissions by 30%. If its current emissions are 2 million tons, what will be the new emissions after the reduction?
Step 1: Identify the current emissions, which is 2 million tons.
Step 2: Calculate 30% of the current emissions. To do this, multiply 2 million tons by 0.3.
Step 3: Perform the multiplication: 0.3 * 2 million tons = 0.6 million tons.
Step 4: Subtract the amount calculated in Step 3 from the current emissions. So, 2 million tons - 0.6 million tons.
Step 5: Perform the subtraction: 2 million tons - 0.6 million tons = 1.4 million tons.
Step 6: The new emissions after the reduction will be 1.4 million tons.
