How many inches of rain do they need to average 2 inches a day? ** They need 730 inches of rain a year to average 2 inches a day because 365 x 2 = 730
How many inches do they need to finish the year with the normal average? ** They need 300 more inches because 730 - 430 = <<730-430=300>>300
How many inches on average do they need to finish the year with the normal average? ** They need 3 inches a day because 300 / 100 = <<300/100=3>>3
