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

### Instruction:
Clara is selling boxes of cookies to raise money for a school trip. There are 3 different types for sale. The first type has 12 cookies per box. The second type has 20 cookies per box, and the third type has 16 cookies per box. If Clara sells 50 boxes of the first type, 80 boxes of the second type, and 70 boxes of the third type, how many cookies does she sell?

### Response:
 Clara anauza biskuti 600 za aina ya kwanza kwa sababu 12*50 = <<12*50=600>>600.
Anauza biskuti 1600 za aina ya pili kwa sababu 20*80 = 1600.
Anauza biskuti 1120 za aina ya tatu kwa sababu 16*70 = 1120.
Hivyo, Clara anauza jumla ya biskuti 3320 kwa sababu 600+1600+1120 = <<3320=3320>>3320.
