To calculate the percent error, we need to find the difference between Simon's estimate and the actual weight of the baby, and then divide that difference by the actual weight.

Simon's estimate: 6.5 pounds
Actual weight: 8.25 pounds

Difference = Actual weight - Simon's estimate = 8.25 - 6.5 = 1.75

Percent error = (Difference / Actual weight) * 100 = (1.75 / 8.25) * 100 = 0.21212... * 100 = 21.2%

So, the percent error of Simon's estimate is 21.2%, which can be rounded to 21%. Therefore, the correct answer is 21%.
