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

### Instruction:
Bran's tuition fee is $90. He does a part-time job that pays him $15 per month and he has a scholarship that takes care of 30% of his tuition fee. If he needs to pay his tuition fee within 3 months, how much does Bran still need to pay?

### Response:
 Ufadhili wa Bran unalipa $90 x 0.30 = $<<90*0.3=27>>27 kwa ada yake ya masomo.
Hivyo, bado anahitaji kulipa $90 - $27 = $<<90-27=63>>63 kwa ada yake ya masomo.
Na Bran ataweza kupata $15 x 3 = $<<15*3=45>>45 baada ya kufanya kazi kwa miezi 3.
Hivyo, bado anahitaji kulipa $63 - $45 = $<<63-45=18>>18.
