A portfolio has a value P$($E$,$S$),$ so that the value P is a function of E$,$ the price of a Euro in Canadian dollars, and S$,$ the level of the TSX stock index. Presently the portfolio is worth $$340,000,$ while a Euro is $$1\mathrm{.}50$ Canadian, and the index is $$S $=18,000.$

If the partial derivatives of P have values $$

$$P

$$E

$=66,000,$ and $$

$$P

$$S

$=19,$ what approximately will the portfolio value be if the price of a Euro goes down by $0\mathrm{.}02$ and the stock index goes down by $322?$A portfolio has a value $P(E,S),$ so that the value $P$ is a function of $E,$ the price of a Euro in Canadian dollars, and

$S,$ the level of the TSX stock index. Presently the portfolio is worth $$340,000,$ while a Euro is $$1\mathrm{.}50$ Canadian,

If the partial derivatives of $P$ have values $\frac{\text{d}\text{e}\text{l}\text{P}}{\text{d}\text{e}\text{l}\text{E}}=66,000,$ and $\frac{\text{d}\text{e}\text{l}\text{P}}{\text{d}\text{e}\text{l}\text{S}}=-19,$ what approximately will the portfolio

value be if the price of a Euro goes down by $0\mathrm{.}02$ and the stock index goes down by $322?$
