The combined gas law is completely defined by one equation.
PV = NRT
where
P = pressure
V = volume
N = quantity of gas
R = a constant depending on what units you want to use
T = absolute temperature
To answer this question you have to assume constant pressure, so:
V2/V1 = T2/T1 = 308.15/288.15 = 1.0694
V2 = 1.0694 x 250 = 267.35 ml
