I have a question about this scenario:
There is 400-acre land which has existing 900 buildings, density is 6/acre, the government wants to increase the density to 8/acre, so what density should be built to the rest of the land in order to bring the density to 8/acre?
I calculate it in this way
3200-900=2300 building left
It’s not a whole number…what should I do about this question? Can someone give me some suggestions? Also, if we meet some questions in the exam, but the result was not a whole number, what should we do? shall we round it to the nearest whole number?
