Answer:
49.5%.
Explanation:
% of salary towards social security tax = (19000/200,000)*100
                                = 9.5%
% of savings = 15%
Yearly mortgage payments = 4333.33*12
                       = 52000
% of mortgage payments = (52000/200,000)*100
                     = 26%
Replacement ratio = 100% - ( 9.5% + 15% + 26%)
                = 49.5%
Therefore, You would expect Lori's wage replacement ratio to be 49.5% at retirement.
