Soru:
A city's annual carbon dioxide (CO\(_2\)) emissions from transportation were 1,000,000 tons. After promoting public transport and cycling, the emissions were reduced by 15%. Calculate the new amount of CO\(_2\) emissions.
Çözüm:
💡 This is a percentage decrease problem. We need to find the new value after a 15% reduction from the original.
- ➡️ Step 1: Find the amount of reduction. A 15% reduction means we calculate 15% of the original amount.
Reduction = 15% of 1,000,000 tons = \( \frac{15}{100} \times 1,000,000 = 0.15 \times 1,000,000 = 150,000 \) tons.
- ➡️ Step 2: Subtract the reduction from the original amount to find the new value.
New Emissions = Original Emissions - Reduction
New Emissions = 1,000,000 tons - 150,000 tons
- ➡️ Step 3: Perform the calculation.
New Emissions = 850,000 tons
✅ The new amount of CO\(_2\) emissions is 850,000 tons.
