A new condo development has 23 floors. Regular floors have 12 units, whereas penthouse floors have only 2 units. If the top 2 floors are assigned for penthouse units, how many units does this condo have in total? Let's answer step by step:
User
If the condo has 23 floors and the top 2 floors are reserved for penthouse then there are 23 - 2 = 21 floors for regular units. If a regular floor has 12 units each, then 21 regular floors would have 12 * 21 = 252 units. If a penthouse floor has 2 units each, then 2 penthouse floors would have 2 * 2 = 4 units. The total units in the property would then be 252 regular + 4 penthouse or 252 + 4 = 256 units. The answer: 256.
