pls mark me brainliest

Step-by-step explanation:

a) The average rainfall per month during these three months(June, July and August) = 50 cm

(b) The total rainfall during the entire year 2014 = 276 cm

(c) The average rainfall per month during the other 9 months = 75.33 cm

Step-by-step explanation:

Given data;

The average rainfall per month in the year 2014 = 23 cm

The total rainfall during the months June, July and August = 150 cm

(a) The average rainfall per month during these three months(June, July and August).

 Total rainfall in these three months / Number of months

= 150/3  

= 50 cm

(b) The total rainfall during the entire year 2014

 = The average rainfall per month throughout the year x Number of months

 = 23 x 12  

 = 276 cm

(c) The average rainfall per month during the other 9 months:

The total rainfall in the other 9 months = Total rainfall throughout the year - Total rainfall for 3 months(June, July, August)

= 276 - 50

= 226 cm

The average rainfall per month during the other 9 months = The total rainfall during the 9 months / Number of months

= 226/9

= 75.33 cm
