Mike watches TV for 4 hours every day. On the days he plays video games he plays for half as long as he watches TV. If he plays video games 3 days a week how long does he spend watching TV and playing video games? Think carefully first, then make a decision:
He plays video games for 4 / 2 = 2 hours a day. He watches TV for 4 * 7 = 28 hours a week. He plays video games for 3 * 2 = 6 hours. So in total he spends 6 + 28 = 34 hours on those activities. So, the answer is 34.
