Answer:

\mathrm{A.\:}\begin{cases}3x+2y=170,\\4x+6y=360\end{cases}\\\\\mathrm{B.\:} \$ 30

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}3x+2y=170,\\4x+6y=360\end{cases}, with variables as defined in the question.

Multiply the first equation by -3 and add both equations to isolate and solve for x:

\begin{cases}-9x-6y=-510,\\4x+6y=360\end{cases}\\-5x=-150,\\x=\fbox{$\$ 30$}.
