Diana gets 30 minutes of video game time for every hour she reads. Her dad decided to raise her reward by 20%. Diana read for 12 hours this week. How many more minutes of video game time will she get as a result of her raise? Give me reasons, before answering the question

Diana’s raise was 20% of her 30 - minute video game time, or 0.20 x 30 minutes = 6 minutes. Diana is now making 30 minutes + 6 - minute raise = 36 minutes for every hour she reads. Diana read 12 hours x 36 minutes of video game time, so she received 432 minutes of video game time after her raise. Before, if Diana read 12 hours x 30 minutes of video game time, she would have received 360 minutes. The amount she received after her raise, 432 minutes – 360 minutes at her old rate = 72 more minutes after her raise. So the final answer is 72.
