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

### Instruction:
 Leonard na ndugu yake Michael walikununua zawadi kwa baba yao. Leonard alinunua mkoba kwa $50 na jozi mbili za viatu vya michezo kwa $100 kila jozi, wakati Michael alinunua begi kwa $100 na jozi mbili za suruali kwa $50 kila jozi. Walitumia kiasi gani jumla?


### Response:
 Jozi mbili za viatu vya michezo zinagharimu 2 x $100 = $<<2*100=200>>200.
Hivyo, Leonard alitumia $50 + $200 = $<<50+200=250>>250.
Jozi mbili za suruali zinagharimu 2 x $50 = $<<2*50=100>>100.
Hivyo, Michael alitumia $100 + $100 = $200.
Hivyo, jumla ya kiasi walichotumia ni $250 + $200 = $<<250+200=450>>450.
