Questions & Step-by-Step Solutions
A country aims to reduce its carbon emissions by 20% over 5 years. If the current emissions are 1,000 tons, what will be the target emissions after 5 years?
Step 1: Identify the current emissions, which is 1,000 tons.
Step 2: Determine the percentage reduction target, which is 20%.
Step 3: Convert the percentage reduction into a decimal by dividing by 100. So, 20% becomes 0.20.
Step 4: Calculate the reduction amount by multiplying the current emissions (1,000 tons) by the decimal (0.20). This gives you 1,000 * 0.20 = 200 tons.
Step 5: Subtract the reduction amount (200 tons) from the current emissions (1,000 tons) to find the target emissions. So, 1,000 - 200 = 800 tons.
