It is possible to calculate the average sales income per low sales month by dividing the sum of sales income of the months recorded 'low' in the questions 9-20 of Household non-farm enterprise module into the number of low sales months. For example, the household that makes ice cream received 135 000 tugrugs in June, 150 000 tugrugs in July and 145 000 tugrugs in August. If income was comparably low in these months, write (135000+150000+145000)/3=143333 in this question.
