What is the work being done when the pressure is 1.5 atm when the volume decreases in a container 35 L to 25 L?

so I set this up as p2= (p1 v1)/v2

1.5x35 /25 = .21

Did I do this correctly?

    At constant pressure, 

    Work, W = PΔV

    W = P(Vf - Vi)

    W = (1.5 atm)(25L - 35L)

    W = -15 L atm

    W = -15 L atm x ( 101.325 J / 1 L atm)

    W = -1520 J

    Since the work is negative, the work is done on the system
