A Correct answer
Explanation

Let the initial price be 100. After 12.5% decrease, price = 100 * 0.875 = 87.5. After another 10% decrease, price = 87.5 * 0.9 = 78.75. The total decrease is 100 - 78.75 = 21.25%.

AI explanation

Let the initial price be 100. A 12.50 percent decrease uses a multiplier of 0.875, making the price 87.5. A further 10 percent decrease uses a multiplier of 0.90, making the final price 87.5 multiplied by 0.90, which is 78.75. The overall percentage decrease is 100 minus 78.75, resulting in 21.25 percent.
