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

### Instruction:
A big snowstorm caused a large amount of snow to fall onto Grandpa's farm, and the wind caused the snow to pile up into a drift.  But on the second day, it warmed up enough that half of the snowdrift melted.  The third day, it snowed again, adding another 6 inches of snow onto the snowdrift.  On the fourth day, another 18 inches of snow fell onto the snowdrift.  If the snowdrift was 34 inches deep at the end of the fourth day, how deep in inches was the drift at the end of the first day?

### Response:
 Mwishoni mwa siku ya kwanza, kifusi cha theluji kilikuwa na kina cha inchi 34. Siku ya pili, nusu ya kifusi cha theluji iliyeyuka, likiacha nusu ya inchi 34, au inchi 17. Siku ya tatu, inchi 6 za theluji zilianguka kwenye kifusi cha theluji, ikileta kina hadi inchi 17 + 6 = <<17+6=23>>23. Siku ya nne, inchi 18 za theluji zilianguka kwenye kifusi cha theluji, ikileta kina hadi inchi 23 + 18 = <<23+18=41>>41. Hii inamaanisha kwamba mwishoni mwa siku ya kwanza, kifusi cha theluji kilikuwa na kina cha inchi 41 - 34 = <<41-34=7>>7.
