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

### Instruction:
A pastry chef is making brownies but is running out of butter.  The recipe he is following calls for 2 ounces of butter for every 1 cup of baking mix; however, it allows 2 ounces of coconut oil to be substituted for the 2 ounces of butter if necessary.  The chef would like to use as much butter as possible before switching over and substituting coconut oil.  If the chef had 4 ounces of butter remaining, and he plans on using 6 cups of baking mix, how many ounces of coconut oil will he end up using?

### Response:
 Kila unga wa siagi wa 2 unatosha kufunika kikombe 1 cha unga wa kupikia, kwa hivyo unga wa siagi uliobaki wa 4 unatosha kufunika 4/2 = <<4/2=2>>2 vikombe vya unga wa kupikia.
Kwa kuwa anapanga kutumia unga wa kupikia kikombe 6, mshonaji atahitaji kutumia vikombe 6 - 2 = <<6-2=4>>4 vya unga wa kupikia ambavyo vitahitaji kutumia mafuta ya nazi kama mbadala.
Kwa kuwa kikombe kimoja cha unga wa kupikia kinahitaji mafuta ya nazi ya unga wa 2, vikombe hivi 4 vitahitaji jumla ya 4*2 = <<4*2=8>>8 unga wa nazi.
