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

### Instruction:
Reynald is the head of the varsity department, and he bought 145 balls. Twenty were soccer balls. There were five more basketballs than the soccer balls. Twice the number of soccer balls were tennis balls.  There were ten more baseballs than the soccer balls, and the rest were volleyballs. How many were volleyballs?

### Response:
 Kulikuwa na mipira ya kikapu 20 + 5 = <<20+5=25>>25.
Kulikuwa na mipira ya tenisi 2 x 20 = <<2*20=40>>40.
Na, kulikuwa na mipira 20 + 10 = <<20+10=30>>30 ya mpira wa kikapu.
Hivyo, Reynald alinunua jumla ya mipira 20 + 25 + 40 + 30 = <<20+25+40+30=115>>115.
Hivyo, mipira ya wavu ilikuwa 145 - 115 = <<145-115=30>>30.
