Les sold some equipment and will receive annual payments of $$400$ for two years and $$350$ for the following two years. Which is the correct present value of multiple annuities formula given a rate of $9$ percent?

Multiple choice question.

$$350\backslash$times $\{[1-(1/1\mathrm{.}094)]/0\mathrm{.}09\}+$ $$50\backslash$times $\{[1-(1/1\mathrm{.}092)]/0\mathrm{.}09\}$

$$350/1\mathrm{.}094+$ $$50/1\mathrm{.}092$

$$350\backslash$times $\{[1-(1/1\mathrm{.}094)]/0\mathrm{.}09\}-$ $$50\backslash$times $\{[1-(1/1\mathrm{.}092)]/0\mathrm{.}09\}$

$$400\backslash$times $\{[1-(1/1\mathrm{.}094)]/0\mathrm{.}09\}-$ $$50\backslash$times $\{[1-(1/1\mathrm{.}092)]/0\mathrm{.}09$
