You know that for a 'payday loan' finance charge may be computed by:

Finance charge $=\frac{\text{N}\text{o}\text{m}\text{i}\text{n}\text{a}\text{l}\text{r}\text{a}\text{t}\text{e}}{\text{N}\text{u}\text{m}\text{b}\text{e}\text{r}of\text{b}\text{i}\text{l}\text{l}\text{i}\text{n}\text{g}\text{p}\text{e}\text{r}\text{i}\text{o}\text{d}\text{s}\text{p}\text{e}\text{r}\text{y}\text{e}\text{a}\text{r}}x$ account balance owed

Nonetheless, you borrow $$500$ for $14$ days, and commit yourself to paying back $$554\mathrm{.}99$ in two weeks. $($Note: year $=365$ days$).$ What is the nominal rate of such a loan?

a$.286\mathrm{.}73\%$

b$.386\mathrm{.}73\%$

c$.486\mathrm{.}73\%$

d$.586\mathrm{.}73\%$

NOTE: Rounding or approximation up to $1$ to $2\%$ is allowed.
