Answer:
2170 kg
Explanation:
since there are 7 days in a week first you calculate the days
930 plus 930 equals 1860 which can feed a pair of elephants for 6 days
then since in one day it takes 310 kg then add 1860 plus 310
and then you get 2170
so, you need 2170 kg of food to feed a pair of elephants in a week
