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

### Instruction:
Frank needs to meet a quota at work for his sales. It’s the beginning of the month and in 30 days he needs to have 50 cars sold. The first three days he sold 5 cars each day. Then the next 4 days he sold 3 cars each day. If the month is 30 days long how many cars does he need to sell for the remaining days to meet his quota?

### Response:
 Frank ameuza magari 5 + 5 + 5 + 3 + 3 + 3 + 3 + 3 = <<5+5+5+3+3+3+3+3=29>>29 hadi sasa.
Hivyo anahitaji kuuza magari 50 - 29 = <<50-29=21>>21 kwa siku zilizobaki ili kukutana na kiwango chake.
