See a solution process below:

First, using the standard order of operation or PEDMAS, first, execute the Multiplication operation within the Parenthesis:

#12.5 + 4 xx (color(red)(1.1) xx color(red)(2) - 2) =>#

#12.5 + 4 xx (2.2 - 2)#

Next, execute the Subtraction operation within the Parenthesis:

#12.5 + 4 xx (color(red)(2.2) - color(red)(2)) =>#

#12.5 + 4 xx 0.2#

Then execute the Multiplication operation:

#12.5 + color(red)(4) xx color(red)(0.2) =>#

#12.5 + 0.8#

Now, execute the remaining Addition operation:

#color(red)(12.5) + color(red)(0.8) => 13.3#
