Explanation
The percent change formula is \(\frac{difference}{original}\times 100\). Remember that the “original” is the
amount before the change. So, in Quantity A, the difference is 200 − 150 = 50, and the original is 200, which yields a 25% change. In Quantity B, the difference is also 50, but the number changes from 150 to 200, so the “original” is 150, which yields roughly a 33.3% change.
Thus, Quantity B is greater.
