Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kuna ghorofa 23.
Ghorofa za juu 2 ni ghorofa za penthouse.
Ghorofa zilizobaki 21 ni ghorofa za kawaida.
Kuna vitengo 12 katika kila ghorofa ya kawaida.
Kuna vitengo 2 katika kila ghorofa ya penthouse.
Jibu ni vitengo 2 * ghorofa 2 za penthouse + vitengo 12 * ghorofa 21 za kawaida = <<2*2+12*21=70>>70 vitengo.
