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

### Instruction:
Every day, Billie bakes 3 pumpkin pies for 11 days and puts them in the refrigerator.  It takes 2 cans of whipped cream to cover 1 pie.  If Tiffany comes over and eats 4 pies, how many cans of whipped cream does Billie need to buy to cover the remaining pies?

### Response:
 Billie anapika mikate 3 x 11 siku = <<3*11=33>>33 mikate.
Bila mikate 4 ambayo Tiffany alikula, kuna mikate 33 - 4 = <<33-4=29>>29 iliyobaki.
Ili kufunika mikate 29, Billie anahitaji makopo 2 ya cream ya kupiga x 29 mikate = <<2*29=58>>58 ya cream ya kupiga.
