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

### Instruction:
A woman needs to buy 16 oz of butter for a dessert recipe.  She can either buy a single 16 oz package of the store-brand butter for $7, or she can buy an 8oz package of store butter for $4 and use a coupon to get an additional two 4 oz packages that normally sell for $2.0 each at a 50% discount (which is applied to each 4oz package separately).  What is the lowest price she can pay for the 16 oz of butter she needs?

### Response:
 Kwa kutumia kuponu, anaweza kununua pakiti mbili za 4 oz za siagi kwa $2.00 kila moja hivyo 2*0.50 = $<<2*0.50=1.00>>1.00
Pamoja na pakiti ya 8 oz na pakiti mbili za 4 oz, atakuwa na 8+4+4 = <<8+4+4=16>>16 oz ya siagi
Ikiwa atanunua pakiti zote tatu, atatumia 4+1+1 = $<<4+1+1=6>>6
