A warehouse has \(n\) widgets to be packed in \(b\) boxes. Each box can hold \(x\) widgets. However, \(n\) is not evenly divisible by \(x,\) so one of the boxes will contain fewer than \(x\) widgets. Which of the following expresses the number of widgets in that box, assuming all other boxes are filled to their capacity of \(x\) widgets?
A. \(n−bx\)
B. \(n−bx+x\)
C. \(n−bx−x\)
D. \(nx−bx\)
E. \(n−x\dfrac{bx}{b−1}\)

Given the information, we get that only \(b-1\) boxes would each have \(x\) widgets. Thus, \(b-1\) boxes would have \((b-1)x\) widgets.Vincen wrote: ↑Tue Jun 02, 2020 7:10 amA warehouse has \(n\) widgets to be packed in \(b\) boxes. Each box can hold \(x\) widgets.

No. of widgets left to be placed in the bth or the last box = \(n-(b-1)x=n-bx+x\) widgets.
The correct answer: B
Hope this helps!

We see that b - 1 boxes will be filled with x widgets each, and they together hold x(b - 1) = bx - x widgets. Therefore, the last box, i.e., the partially filled box, will hold n - (bx - x) = n - bx + x widgets.
Answer: B
