Hi$,$ i think it is a mistake here

Free Cash Flow to Equity $($FCFE$)$:

FCFE $=$ CFO $+\backslash$Delta NWC $$ Principal Repayment $$ Capital Expenditure

$=$ $$51\mathrm{.}4$ mln $-$ $$10$ mln $-$ $$25$ mln $-$ $$20$ mln

$=-$ $$3\mathrm{.}60$ million

Free Cash Flow to the Firm $($FCFF$)$:

FCFF $=$ FCFE $+$ Interest Expense x $(1$ Tax rate$)$

$=-$ $$13\mathrm{.}6$ mln $+$ $$5$ mln x $(10\mathrm{.}40)$

$=-$ $$10\mathrm{.}60$ million

It is different number in FCFF formula, namely $-$$$13,6,$ but you calculated FCFE as $-$$$3\mathrm{.}6$

Please explain
