During the last 365 days it was sunny 5 days less than 4 times the number of rainy days. How many days did it rain?

This question does not allow for days when it is neither sunny nor rainy (for example, cloudy or snow). There are also days that have both sun and rain.
There are many possible answers. They should come up with better questions than this.
What they probably want you to do is solve the equation
R + (4R 5) = 365
R us the number of rainy days. 
Ok, thank you this is very helpful! I was trying to use 4(R)5=365. The question was really throwing me off.
