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

### Instruction:
John is working as an IT specialist. He repairs broken computers. One day he had to fix 20 computers. 20% of them were unfixable, and 40% of them needed to wait a few days for spare parts to come. The rest John was able to fix right away. How many computers John was able to fix right away?

### Response:
 Kati ya kompyuta zote, asilimia 100 - 40 - 20 = 40 zilirekebishwa mara moja.
Hivyo, kati ya kompyuta 20, John alirekebisha 40/100 * 20 = <<40/100*20=8>>8.
