Sales tax rate
19.80349.80×100%5.66%\begin{lgathered}\frac{19.80}{349.80} \times 100\% \\ 5.66\%\end{lgathered}
349.80
19.80

Answer:
The vertex is the point 
Step-by-step explanation:
we know that
The equation of the absolute value in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex
In this problem we have
so
---> the vertex represent a maximum
therefore
The vertex is the point
