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

### Instruction:
Paul made two bank transfers of $90 and $60 respectively. A service charge of 2% was added to each transaction. If the second transaction was reversed (without the service charge), what is his account balance now if it was $400 before he made any of the transfers?

### Response:
 2% ya $90 ni (2/100)*$90 = $<<(2/100)*90=1.8>>1.8
2% ya $60 ni (2/100)*$60 = $<<(2/100)*60=1.2>>1.2
Uhamisho wa pili ulirudishwa bila ada ya huduma, hivyo tu $90+$1.8+$1.2 = $<<90+1.8+1.2=93>>93 zilidondolewa kutoka kwenye akaunti yake
Atakuwa na salio la $400-$93 = $307
