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

### Instruction:
Larry started off having 150 channels from his cable company.  They took 20 channels away and replaced those with 12 channels.  He called the company and asked if he could reduce his package by 10 more channels but add the sports package which is 8 channels.  He realizes that he didn't add the supreme sports package.  He calls back and that package adds 7 more channels.  How many channels does Larry have?

### Response:
 Alianza na vituo 150 na waliyachukua vituo 20 na kuongeza vituo 12, hivyo ana vituo 150-20+12 = <<150-20+12=142>>142.
Anapiga simu na kuomba kupunguza vituo vyake 142 kwa vituo 10 na kuongeza vituo 8 vya michezo, hivyo ana vituo 142-10+8 = <<142-10+8=140>>140.
Aliagiza pakiti ya michezo isiyo sahihi na ile mpya inaongeza vituo 7 zaidi, kwa jumla ya vituo 140+7 = <<140+7=147>>147.
