Given that Patrick had 93 cameras and purchased 86 more, the total number of cameras he has is
= 93 + 86
= 179 cameras
Given that one box can only hold 65 cameras, the total number of boxes required can be derived as
= 179/65
= 2 49/65
Hence he would require 3 boxes. The first will hold 65, the next will hold another 65 and the third will hold the remaining 49 cameras. Thus he can ship 2 full boxes while the 3rd will only hold 49 camera
