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

### Instruction:
Robi and Rudy contributed money to start a business that could earn them profit. Robi contributed $4000, and Rudy contributed 1/4 more money than Robi. If they made a profit of 20 percent of the total amount and decided to share the profits equally, calculate the amount of money each got.

### Response:
 Ikiwa Robi alitoa $4000, basi Rudy alitoa pesa zaidi ya Robi kwa $1000.
Jumla ya pesa ambazo Rudy alitoa ni $4000+$1000 = $<<4000+1000=5000>>5000
Pamoja, walichangia jumla ya $5000+$4000 = $<<5000+4000=9000>>9000
Walipata faida ya asilimia 20, jumla ya $9000 x 20/100 = $<<9000*20/100=1800>>1800
Walipoamua kugawana faida kwa usawa, kila mmoja alipokea $1800/2 = $<<1800/2=900>>900
