Adding a strong acid to a buffer please help i cant figure this one out?

A beaker with 110 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 . 4.30mL of a 0.330 M solution is added to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.Adding a strong acid to a buffer please help i cant figure this one out?
you did not give the identity of the added acid

HCl, H2SO4,..., ???
