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

### Instruction:
Carl is having a party on Saturday and is inviting 15 guests. He would like to make sure everyone, including himself, has at least 2 glasses of punch. Each glass holds 12 ounces of punch. How many ounces of punch does he need to buy for the party?

### Response:
 Kukiwa na Carl, kutakuwa na watu 15 + 1 = <<15+1=16>>16 kwenye sherehe.
Carl anataka 2 glasi x 12 ounces = <<2*12=24>>24 ounces kwa kila mtu.
Carl anahitaji kununua unga wa punch wa 16 x 24 = <<16*24=384>>384 ounces.
