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? Let's answer step by step:
Radhika was given 12 video games on Christmas and 8 video games on her birthday, so she was given 12 + 8 = 20 video games. She had 1 / 2 this many before she was given gifts, 20 / 2 = 10 video games she already owned. She was given 20 video games and had 10 already, 20 + 10 = 30 video games. Now Radhika has 30 video games. The answer: 30.
