Answer:
6 rainy days
Explanation:
Given that :
Number of days = 30
Let:
number of rainy days = x
From the question, for every rainy day, there wer 4 sunny days ;
Hence,
Number of sunny days = 4x
Therefore,;
Number of rainy days + number of sunny days = number of days in the month
x + 4x = 30
5x = 30
Divide both sides by 5
5x / 5 = 30 / 5
x = 6
Hence, there were 6 rainy days in the month
