A hotel has 128 rooms on each floor there are 4 rooms n all. if 334 rooms are clean, how many rooms still need to be cleaned?

So first, you have to find how many rooms total there are. If there are 128 rooms on each floor and 4 floors total then you have to do 128 x 4 = 512. So, if there are 512 rooms total and 334 are clean already to find how many that need to be cleaned are left you have to subtract 334 from 512.

512 - 334 = 178

So, there are 178 rooms left that need to be cleaned.

R u trying to say theres 128 rooms in each floor and theres 4 floors becaude if its meant to say that there is 178 rooms left to clean
