Reading 14 EOC #10 400, care, following, included, question

mfleming1983

The question/IPS never addressed his mother’s health care needs as part of the return requirement, so I included the following net of pension income:
(3500-1500)*12 = 24,000.
Added this to 50,400 in order to obtain 74,400 which equates to a 9.3 percent pre inflation and 10.3 percent post inflation.
The guideline answer did not seem to take this into account.
Any thoughts?
