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

### Instruction:
Robby, Jaylen and Miranda are employed at a Cheesecake factory, earning $10 per hour. They work 10 hours a day, five days a week. Robby saves 2/5 of his salary, Jaylene saves 3/5 of his salary, while Miranda saves half of her salary. What are the combined savings of the three employees after four weeks?

### Response:
 Kwa siku, kila mmoja wao anapata $10 * 10 = $100.
Baada ya kufanya kazi kwa siku tano, mfanyakazi analipwa $100 * 5 = $500.
Kwa mwezi, mfanyakazi analipwa $500 * 4 = $2000.
Robby anaokoa 2/5 * $2000 = $800 kutoka kwa mshahara wake.
Jaylene anaokoa 3/5 * $2000 = $1200 kutoka kwa mshahara wake.
Miranda anaokoa 1/2 * $2000 = $1000 kutoka kwa mshahara wake.
Jumla ya akiba kwa wafanyakazi watatu ni $1000 + $1200 + $800 = $3000.
