A beaker with 200 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.40 mL of a 0.400 \it M \rm HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.

I've tried using the Henderson Hasselbalch equation but the answer isn't coming out right.
