Math problem

The startup division made 80% of 1/2 of the established division. The startup division’s growth was 1/3 greater than the established division’s. If the divisions made $280,000 combined, how much did the startup division make?

I don't understand what growth has to do with it?

80% of 1/2 = 40% of the established.

If established = 100 % and startup = 40%
that's a ratio of 40 to 100 so the startup division
made 80K and the established division
made 200K.
