[510×(1-96%y)-(400-y)]×(1-10%)
[510×(1-96%y)-(400-y)]×(1-10%)

[510×(1-96%y)-(400-y)]×(1-10%)
[510×(1-96%y)-(400-y)]×(1-10%)
=[510×0.04y-(400-y)]×0.9
=[20.4y-400+y]×0.9
=(21.4y-400)×0.9
=19.26y-360

什么问题？

[510×(1-96%y)-(400-y)]×(1-10%)
=[510-510×0.96y-(400-y)]×0.9
=[510-400-（510×0.96-1）y]×0.9
=[110-488.6y]×0.9
=99-440.64y
