To solve for absolute pressure, you will need this formula:
Where:
= absolute pressure
= atmospheric pressure
r (rho) = density
g = acceleration due to gravity constant
h = depth (in this case)
rgh is the formula for pressure of fluids
So with your given, we just need to insert it into the formula:
= 1.01 x 
x (1,025 
x 9.8 
x 15 m
= 1.01 x + 150,675
= 1.01 x + 1.51 x
= 2.52 x 
This is your absolute pressure.
