The acoustical intensity I of a sound wave is proportional to the square of the pressure amplitude

Question:

The acoustical intensity I of a sound wave is proportional to the square of the pressure amplitude P and inversely proportional to the velocity v of the wave. If I = 0.474 W/m² for P = 20.0 Pa and v = 346 m/s, find I if P = 15.0 Pa and v = 320 m/s.
