### Instruction:
 Alvin ana miti ya nazi ambayo hutoa nazi 5 kila moja. Ikiwa nazi moja inaweza kuuzwa kwa $3 na Alvin anahitaji $90, anapaswa kuvuna miti mingapi ya nazi?


### Response:
 Alvin anahitaji 90 / 3 = <<90/3=30>>30 za nazi ili apate $90
Hivyo anahitaji 30 / 5 = <<30/5=6>>6 miti ya nazi.
