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

### Instruction:
Ann is baking cookies. She bakes three dozen oatmeal raisin cookies, two dozen sugar cookies, and four dozen chocolate chip cookies. Ann gives away two dozen oatmeal raisin cookies, 1.5 dozen sugar cookies, and 2.5 dozen chocolate chip cookies. How many total cookies does she keep?

### Response:
 Ann alikuwa na 3 dazeni ya mikate ya oatmeal raisin - 2 dazeni = <<3-2=1>>1 dazeni ya mikate ya oatmeal raisin iliyobaki.
Ann alikuwa na 2 dazeni ya mikate ya sukari - 1.5 dazeni = <<2-1.5=.5>>0.5 dazeni ya mikate ya sukari iliyobaki.
Ann alikuwa na 4 dazeni ya mikate ya chocolate chip - 2.5 dazeni = 1.5 dazeni ya mikate ya chocolate chip iliyobaki.
Ann ana jumla ya 1 + 0.5 + 1.5 dazeni ya mikate = <<1+.5+1.5=3>>3 dazeni ya mikate, au 36 mikate.
