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

### Instruction:
Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets?

### Response:
 Tiketi za ndugu zake wote zitamgharimu $10 * 2 = $20.
Kununua tiketi kwa wote, itamgharimu Isabelle $20 + $20 = $40.
Kwa kuwa yeye na ndugu zake wameokoa jumla ya $5 + $5 = $10, anahitaji kupata $40 - $10 = $30 zaidi ili aweze kumudu tiketi hizo.
Atahitaji kufanya kazi $30 / $3 kwa wiki = 10 wiki ili aweze kumudu tiketi hizo.
