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

### Instruction:
An archer needs to practice.  He intends to shoot 200 shots 4 days a week.  He is able to recover 20% of his arrows.  The arrows he uses cost $5.5 per arrow.  His team agrees to pay for 70% of the cost of his arrows.  How much does he spend for arrows a week?

### Response:
 Mshambuliaji anafyatua mishale 200 * 4 siku = <<200*4=800>>800 mishale kwa wiki.
Anapata tena 20% ya mishale yake, hivyo anatumia <<800*0.8=640>>640 mishale kwa wiki.
Anachangia 30% ya gharama ya mishale yake, hivyo anatumia <<640*5.5*0.3=1152>>1152 dola kwa wiki.
