1.25*67.875+0.125*6787.5+125*0.53375
=1.25*67.875+1.25*678.75+1.25*53.375
=1.25*(67.875+53.375)+1.25*678.75
=1.25*121.25+1.25*678.75
=1.25*(121.25+678.75)
=1.25*800
=125*8
=1000
=1.25*67.875+1.25*678.75+1.25*53.375
=1.25*(67.875+53.375)+1.25*678.75
=1.25*121.25+1.25*678.75
=1.25*(121.25+678.75)
=1.25*800
=125*8
=1000
