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

### Instruction:
 Mary anataka kupika mikate 10 ya tufaha kwa ajili ya tukio la hisani. Kila mkate unahitaji tufaha 8 na tayari amekusanya tufaha 50 kutoka kwenye miti katika bustani yake. Anahitaji tufaha ngapi zaidi kununua ili apike mikate yote 10?


### Response:
 Ili apike mikate 10, Mary anahitaji tufaha 8 * 10 = <<8*10=80>>80.
Kwa kuwa ana tufaha 50, anahitaji kununua 80 - 50 = <<80-50=30>>30 zaidi.
