Jupiter has a black body temperature of 125K, but this is 20 K higher than the temperature that would be calculated from absorbed solar radiation alone. From this information, calculate the ratio of emitted radiation to absorbed solar radiation on Jupiter.
I started using
W = sigma * area * temp^4
Is that of any help?
Or are they any hints that I might try to start with?

Stefan–Boltzmann law is correct.
No need to include area; just use the ratio of the two in terms of their irradiance, comparing the 4th power of the temperature of the two.
