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

### Instruction:
Mr. and Mrs. McPherson have to renew their rent by the end of the year. They agreed that Mrs. McPherson would raise 30% of the money. If their rent is $1200 per year, how much does Mr. McPherson need to raise to complete the rent?

### Response:
 30% ya $1200 = (30/100)*$1200 = $<<(30/100)*1200=360>>360
Bi McPherson atalipa $360, hivyo Bwana McPherson anahitaji kuchangia $1200-$360 = $<<1200-360=840>>840
