Ooo this one's a hard one... I think it's A. 19 ;) lol
Store A
50*5%=2.5
50-2.5=47.5
47.5+(6%*47.5)=$50.35
Store B
20%*60=12
60-12=48
48+(6%*48)=$50.88
I would but the watch from store A because it would be 53 cents cheaper.
If there are 2 office rooms, there are 6 rooms that aren't office rooms. So the percentage of non-office rooms can be expressed as:
# of non-office rooms/total rooms
or
6/8
In percentage, this is 75%
Hope this helps!
