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

### Instruction:
 Marlon ana kadi ya zawadi yenye thamani ya $200. Alitumia nusu yake Jumatatu na robo ya kiasi kilichosalia Jumanne. Kiasi gani kilibaki kwenye kadi yake ya zawadi?


### Response:
 Kwa kuwa Marlon alitumia nusu ya kadi ya zawadi, basi nusu yake ambayo ni $200/2 = $<<200/2=100>>100 ilibaki Jumatatu.
Kisha Jumanne, alitumia $100/4 = $<<100/4=25>>25.
Hivyo, ana $100 - $25 = $<<100-25=75>>75 zilizobaki kwenye kadi yake ya zawadi.
