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

### Instruction:
Mike has to get an x-ray and an MRI.  The x-ray is $250 and the MRI is triple that cost.  Insurance covers 80%.  How much did he pay?

### Response:
 MRI inagharimu 250*3=$<<250*3=750>>750
Hivyo kati ya vitu viwili anacholipa ni 250+750=$<<250+750=1000>>1000
Bima ilifidia 1000*.8=$<<1000*.8=800>>800
Hivyo alilazimika kulipa 1000-800=$<<1000-800=200>>200
