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

### Instruction:
A used car lot has 24 cars and motorcycles (in total) for sale. A third of the vehicles are motorcycles, and a quarter of the cars have a spare tire included. How many tires are on the used car lot’s vehicles in all?

### Response:
 Duka la magari ya kutumika lina pikipiki 24 / 3 = <<24/3=8>>8 zenye matairi 2 kila moja.
Duka lina magari 24 - 8 = <<24-8=16>>16 yanayouzwa.
Kuna magari 16 / 4 = 4 yenye tairi ya ziada zenye matairi 5 kila moja.
Duka lina magari 16 - 4 = <<16-4=12>>12 yenye matairi 4 kila moja.
Hivyo, magari ya duka la magari ya kutumika yana matairi 12 * 4 + 4 * 5 + 8 * 2 = 48 + 20 + 16 = <<12*4+4*5+8*2=84>>84 kwa jumla.
