If last year usage was 1,200,000 kWh and it reduces by 12%, what is this year's usage?

Explanation:
When you apply a percentage decrease, you multiply the original amount by 1 minus the decrease rate. Here, a 12% drop means multiply by 0.88. So 1,200,000 kWh × 0.88 = 1,056,000 kWh. Another way is to find 12% of 1,200,000, which is 144,000 kWh, and subtract it from the original: 1,200,000 − 144,000 = 1,056,000 kWh. This is this year’s usage. The other numbers would reflect no change, an increase, or a different calculation, not a 12% reduction.
