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

### Instruction:
A business executive is going on a four day vacation where he will be unable to answer emails.  The first day he is gone, he receives 16 new emails.  On each of the following days, he receives half as many new emails as he received on the prior day.  At the end of his four day vacation, how many new emails will he have received in total?

### Response:
 Siku ya pili, mkurugenzi anapokea barua pepe mpya 16 / 2 = <<16/2=8>>8.
Siku ya tatu, anapokea barua pepe mpya 8 / 2 = <<8/2=4>>4.
Siku ya nne, anapokea barua pepe mpya 4 / 2 = <<4/2=2>>2.
Kwa hivyo, katika likizo yote, atapokea jumla ya barua pepe mpya 16 + 8 + 4 + 2 = <<16+8+4+2=30>>30.
