Answer:

Final payment is: #$104.25#

Explanation:

There are sat least 2 ways of calculating this. You put everything together in one go or can split the process. I am going to split it.

#color(blue)("Determine the deposit")#

The deposit is: #25/200xx$139.00 =$34.75 #

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(blue)("Determine the final payment")#

#$139.00#
#ul($color(white)(1)34.75) larr" subtract"#

Write as:
#$13cancel(9)^(8) .cancel(0)^(9)cancel(0)^(10)#
#ul($color(white)(1)3color(white)(.)4color(white)(.). color(white)(.)7color(white)(..)5) larr" subtract"#
#$104color(white)(..).color(white)(.)2color(white)(..)5#

Final payment is: #$104.25#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(red)("The other method")#

Let the final payment be #x#

#x=$139(100/100-25/100)#

#x=$139(75/100)=$104.25#
