In essence, for 1 room, number of worker is inversely proportional to number of days. For 1 room, if worker increase, days decrease. If worker decrease, days increase.
For room and the number of days, they are directly proportional. More room, more days to paint. Less room, less days to paint.
Hope you understand! Good luck!
