During my three-week stay in Walla Walla, Washington, it rained for 7 days, it was sunny for 11 days, and it was overcast without rain for 3 days. The next time I go to Walla Walla, I'm staying for a full leap year, or 366 days. If we assume Walla Walla will have the same ratio of rainy, sunny, and overcast days that I experienced on my last visit, how many days in my year should I expect it to rain?

Rain : sunny : overcast

7:11:3

7x + 11x + 3x = 366

21x = 366

x = 366/21

x = 17.43

7 (17.43) = 122.01 days rain

11 (17.43) = 191.73 days sunny

3 (17.43) = 52.29 days overcast
