$209

Explanation:

Let the total sum be #x#
Using ratio but in the format of a fraction.

#("isabella")/("Shane")->4/15 larr # as a ratio

So we have 4 parts for Isabella and 15 parts for Shane. This gives a total count of parts as #4+15=19# parts

As a fraction of the whole Isabella #->4/(4+15)x=$44#

#4/19x=$44#

#x=19/4xx$44= $209#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The combined value is #$209#
