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

### Instruction:
Margo donated $4300 to Jayden's fundraising campaign. If Julie donated $4700 to Jayden's campaign, What's half the difference in the amount they contributed?

### Response:
 Ikiwa Julie alitoa mchango wa $4700 kwenye kampeni ya Jayden, na Margo alitoa mchango wa $4300, tofauti ya michango yao ni $4700-$4300=$<<4700-4300=400>>400
Nusu ya tofauti ya michango waliyotoa ni 1/2*$400=$<<400/2=200>>200
