break even and cvp

I a trying to do a question with maximum capacity, I need to find out what break even point is but do not know where maximum capacity fits in this question.

I already know to find break even that i must find contribution less fixed cost

also the question also contains variable selling and admin cost and fixed selling and admin cost do I leave this for another part in the question or or do I add it with variable and fixed manufacturing cost?

Please assist !! Many thanks
