Suppose that Etsy $($an e$-$commerce site focused on handmade or vintage items$)$ necklace vendors compete in a Bertrand $\frac{?}{\text{b}\text{a}\text{r}}(E{)}^{}{?}^{\frac{?}{\text{b}\text{a}\text{r}}(lon{)}^{}}{q}_1=300-15p_1+10p_2$

Where $p_1$ is the price of style $1,$ and $p_2$ is the price of style $2,$ produced by vendor $2.$ Demand for style $2$ is

${?}^{}{q}_2=500-10p_2+5p_1.$

The costs of providing these necklaces are $C_1=q_1$ and $C_2=0\mathrm{.}75q_2$ respectively. The equilibrium price of style $1$ is $

$26\mathrm{.}32$

$30\mathrm{.}66$

$20\mathrm{.}62$

$32\mathrm{.}54$
