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

### Instruction:
Since the 40th president launched his reelection campaign today, he has raised $10,000 in campaign funds. His friends raised 40% of this amount and his family raised 30% of the remaining amount.  The rest of the funds are from his own savings for the election. How much did he save for the presidency?

### Response:
 Jumla ya fedha zilizochangwa na marafiki ni 40/100*$10000 = $<<40/100*10000=4000>>4000
Baada ya kuchangia marafiki, rais wa 40 amepata $10000-$4000 = $6000
Familia imechangia 30/100*$6000 = $1800
Kama familia imechangia $1800, akiba ya rais wa 40 kwa ajili ya kampeni ni $6000-$1800 = $4200
