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

### Instruction:
 Lift iko ghorofa ya 9. Inashuka ghorofa 7, kisha inapanda ghorofa 3, kisha inapanda ghorofa 8. Ikiwa lift iko juu kabisa, kuna jumla ya ghorofa ngapi katika jengo hilo?


### Response:
 Kutoka ghorofa ya 9, lift ilishuka hadi ghorofa ya 9 - 7 = <<9-7=2>>2.
Kisha ilipanda hadi ghorofa ya 2 + 3 = <<2+3=5>>5.
Kisha, ilipanda hadi ghorofa ya 5 + 8 = <<5+8=13>>13; hivyo kuna jumla ya ghorofa 13 katika jengo hilo.
