Question- Apply the Henderson Hasselbach equation to calculate the percentage of Articaine that is in the neutral form at pH 7.2
pKa of Articaine is 7.6

The answer is 29% but I keep getting 39%. Please explain how you derived the answer because I take 10^-.4 =.39 x 100 = 39% once I subtract the pKa from pH

If possible just a brief explanation how you got the answer?
