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

### Instruction:
Otto’s local kitchen supply store charges $5.00 for the first knife that you need sharpened.  They charge $4.00 for the next 3 knives and $3.00 for any knife after that.  If Otto has 9 knives that need to be sharpened, how much will it cost to sharpen his knives?

### Response:
 Visu 2,3,4 zitagharimu $4.00 kila moja kufanywa mkali hivyo zitagharimu 3*4 = $12.00
Visu 5-9 zitagharimu $3.00 kila moja kufanywa mkali hivyo zitagharimu 5*3 = $<<5*3=15.00>>15.00
Ikiwa kisu cha kwanza kitagharimu $5.00 kufanywa mkali na visu nyingine 8 zitagharimu $12.00 na $15.00 kufanywa mkali basi itagharimu Otto 5+12+15 = $<<5+12+15=32.00>>32.00 kufanya visu zake zote kuwa mkali
