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

### Instruction:
After receiving the $2000 stimulus check, Mr. Eithan decided to share the amount with his family. He gave 2/5 of the amount to his wife, 2/5 of the remaining amount to his first son, 40% of the remaining amount to his second son, and kept the remaining in their family savings account. Calculate the total amount he kept in the family's savings account.

### Response:
 Jumla ya pesa Bwana Eithan aliyompa mkewe ni 2/5*2000 = $<<2/5*2000=800>>800
Baada ya kumpa mkewe $800, alibakiwa na $2000-$800 = $1200
Alimpa mtoto wake wa kwanza 2/5 ya kiasi kilichobaki baada ya kumpa mkewe $800, jumla ya 2/5*$1200 = $<<2/5*1200=480>>480
Kiasi kilichobaki baada ya kumpa mtoto wake wa kwanza sehemu yake ni $1200-$480 = $<<1200-480=720>>720
Kisha alimpa mtoto wake wa pili 40/100*720 = $<<40/100*720=288>>288 ya pesa.
Baada ya kumpa mtoto wake wa pili $288, kiasi cha pesa kilichobaki ambacho alikiweka katika akaunti ya akiba ya familia ni $720-$288=$432
