Question 1205377
<font color=black size=3>
x = number of boxes, some nonnegative whole number
48x = weight of all those boxes, ignoring your weight
48x + 175 = weight of those boxes plus your weight as well


"The weight cannot exceed 1400 lbs". This is the highest we can go. It's the ceiling value.
Either TotalWeight = 1400 or TotalWeight < 1400
It leads to {{{48x+175 <= 1400}}}
I'll let the student solve this inequality if your teacher requires it.


Note: The info about moving boxes from the bottom floor to the 6th floor is added info meant as a distraction.
