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

### Instruction:
The batting cage sells golf balls by the dozen. They charge $30 for 3 dozen. Dan buys 5 dozen, Gus buys 2 dozen, and Chris buys 48 golf balls. How many golf balls do they purchase in total, assuming 12 golf balls are 1 dozen?

### Response:
 Kizazi kimoja ni mipira 12 ya gofu. Hivyo kizazi cha 3 ni mipira 3 x 12 = <<3*12=36>>36 ya gofu.
Wanatoza $30 kwa kizazi cha 3, hivyo kizazi kimoja ni $30/3 = <<30/3=10>>10 dola.
Dan ananunua kizazi cha 5 = 5 x 12 = <<5*12=60>>60 mipira ya gofu.
Gus ananunua kizazi cha 2 = 2 x 12 = <<2*12=24>>24 mipira ya gofu.
Chris ananunua mipira 48 ya gofu.
Hivyo jumla ya mipira ya gofu wanayonunua ni 60+24+48 = <<60+24+48=132>>132 mipira ya gofu.
