Your definition is not very clear and test data very limited , but try this:

Code:
awk '(NR==FNR) {A=$1} (NR!=FNR) & (FNR != 28) {FS=","; print;} (NR!=FNR) & (FNR==28) { $2 = A/3 + 1; $NF=A; print}'  file1 file2

where file1 is the first file with the last line of interest and file 2 is the file with the line you want to replace.

ttk::label(n)							 Tk Themed Widget						     ttk::label(n)

__________________________________________________________________________________________________________________________________________________

NAME

       ttk::label - Display a text string and/or image

SYNOPSIS

       ttk::label pathName ?options?
_________________________________________________________________

DESCRIPTION

       A ttk::label widget displays a textual label and/or image.  The label may be linked to a Tcl variable to automatically change the displayed
       text.

STANDARD OPTIONS

       -class		     -compound		  -cursor
       -image		     -style		  -takefocus
       -text		     -textvariable	  -underline
       -width

       See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       [-anchor anchor] Specifies how the information in the widget is positioned relative to the inner margins.  Legal values are n, ne,  e,  se,
       s,  sw,	w, nw, and center.  See also -justify.	[-background frameColor] The widget's background color.  If unspecified, the theme default
       is used.  [-font font] Font to use for label text.  [-foreground textColor] The widget's  foreground  color.   If  unspecified,	the  theme
       default	is  used.   [-justify justify]	If there are multiple lines of text, specifies how the lines are laid out relative to one another.
       One of left, center, or right.  See also -anchor.  [-padding padding] Specifies the amount of extra space to allocate for the widget.   The
       padding is a list of up to four length specifications left top right bottom.  If fewer than four elements are specified, bottom defaults to
       top, right defaults to left, and top defaults to left.  [-relief relief] Specifies the 3-D effect desired for  the  widget  border.   Valid
       values  are flat, groove, raised, ridge, solid, and sunken.  [-text text] Specifies a text string to be displayed inside the widget (unless
       overridden by -textvariable).  [-wraplength wrapLength] Specifies the maximum line length (in pixels).  If this	option	is  less  than	or
       equal to zero, then automatic wrapping is not performed; otherwise the text is split into lines such that no line is longer than the speci-
       fied value.
