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

### Instruction:
Bob and Johnny have a leaf raking business. They charge $4 for each bag of leaves they rake. On Monday they raked 5 bags of leaves. On Tuesday they raked 3 bags of leaves. On Wednesday, they counted their money and found they had $68 for all three days. How many bags of leaves did they rake on Wednesday?

### Response:
 Kwa kuunganisha Jumatatu na Jumanne, walifagia mifuko 5 + 3 = <<5+3=8>>8 ya majani.
Walipata 8 * $4 = $<<8*4=32>>32 kwa siku mbili za kwanza.
Kwa kazi ya Jumatano walipata $68 - $32 = $<<68-32=36>>36.
Hivyo, walifagia mifuko $36 / $4 = <<36/4=9>>9 ya majani Jumatano.
