365 days in year. It snows 30 days of the year. There are meetings 50 days in the year. How many meeting days will not be snow days?

335 days will not be snowy days, I say this because I subtracted 30 from 365, in order to get the snowy days out the way ... so you have 335 day of no snow, do you understand, if not i can explain it better for you
