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

### Instruction:
 Cory ana $20.00 na anataka kununua pakiti mbili za pipi ambazo kila moja inagharimu $49.00. Cory anahitaji pesa kiasi gani ili aweze kununua pakiti hizo za pipi?


### Response:
 Pakiti mbili za pipi zinagharimu $49 x 2 = $<<49*2=98>>98.
Hivyo, Cory anahitaji $98 - $20 = $<<98-20=78>>78 ili aweze kununua pakiti mbili za pipi.
