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

### Instruction:
Radhika got a new gaming system and asked everyone to get her games as gifts to add to the games she already has that she bought with her gaming system. On Christmas, she is given 12 new video games. On her birthday in February, she is given 8 more video games. Radhika already owned 1/2 the number of games as what she was given on Christmas and her birthday. How many video games does she own now?

### Response:
 Radhika alipewa michezo ya video 12 siku ya Krismasi na michezo ya video 8 siku yake ya kuzaliwa, hivyo alipewa jumla ya michezo ya video 12 + 8 = <<12+8=20>>20.
Alikuwa na 1/2 ya idadi hii kabla hajapewa zawadi, 20 / 2 = <<20/2=10>>10 michezo ya video ambayo tayari alikuwa nayo.
Alipewa michezo ya video 20 na alikuwa na 10 tayari, 20 + 10 = <<20+10=30>>30 michezo ya video.
Sasa Radhika anamiliki michezo ya video 30.
