Angela slept 6.5 hours every night in December. She decided she should get more sleep and began sleeping 8.5 hours a night in January. How much more sleep did Angela get in January? Let's think first. Chain of thought:
Angela slept 8.5 6.5 = 2 more hours each night in January. There are 31 days in December and January, so Angela 2 x 31 = 62 more hours sleep.
Therefore, the answer is 62.
