 
 <prompt> Isabelle don get work so she fit save money reach make she fit go concert with her two brothers. Her ticket cost $20. Her brothers both get pikin discount, and each of their tickets cost $10. Her brothers don save $5 together and Isabelle don save $5. If her work dey pay $3 per week, how many weeks she go need work to fit afford the tickets? <response>: ```The tickets for both of her brothers go cost am $10 * 2 = $20.
To buy tickets for all of them, e go cost Isabelle $20 + $20 = $40.
Between all of them, dem don save total of $5 + $5 = $10.
Since dem don save $10 already, she go need hustle extra $40 - $10 = $30 to fit buy the tickets.
Since she dey make $3 per week, e go take am $30 / ($3/week) = <<30/(3)=10>>10 weeks to save enough money for all of the tickets.

The final answer: 10.```
