19. 1/4 of 320 is 80
Therefore, 80 cities have both museums, 240 have only art, 330 have only nature. So the total number of cities with nature museums is 410.
(Hopefully I did that right....)

23. This one, you just repeated one of the steps.
Step 1: 39
Step 2: 41 -->39+2
Step 3: 20.5 -->41/2
Answer: 20

*Working on other problems.
