Question 1124795
<font face="Times New Roman" size="+2">


Before they started, they had 156 times 125 daily rations.


After n people left, they had (156 - n)(125 + 70) daily rations.


Since they didn't change the amount of food they had, these two expressions must be equal.


Set them equal to each other and solve the resulting equation for n.
