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

### Instruction:
Keith bought 8 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 46 cards left. How many cards did Keith start with?

### Response:
 Mbwa wa Keith alikula nusu ya mkusanyiko wake hivyo kuna kadi 2 * 46 = <<2*46=92>>92 kwenye mkusanyiko wa asili wa Keith.
Keith aliongeza kadi 8 mpya kwenye mkusanyiko wake hivyo mkusanyiko wake wa asili ulikuwa na kadi 92 - 8 = <<92-8=84>>84.
