the correct question is
What is the sum of the following amounts of money 10.15 31.60 34.75 40.00 69.25 54.75?
we have that
[10.15+31.60+34.75+40.00+69.25+54.75]
=[(10+0.15)+(31+0.60)+(34+0.75)+(40)+(69+0.25)+(54+0.75)]
=[10+31+34+40+69+54]+[0.15+0.60+0.75+0.25+0.75]
=[238]+[2.5]
=240.50
the answer is
240.50
