C Correct answer
Explanation

The increase in stamps is 285 - 125 = 160. The percentage increase is (increase / original) * 100 = (160 / 125) * 100 = 1.28 * 100 = 128 percent.

AI explanation

To find the percentage increase, we calculate the difference between the new value and the original value, divide by the original value, and multiply by 100. The increase is 285 minus 125, which equals 160 stamps. Therefore, the percentage increase is (160 divided by 125) multiplied by 100, resulting in 128%.
