Question

A house on the market was valued at $378,000. After several years, the value decreased by 19%. By how much did the house’s value decrease in dollars? What is the current value of the house?

Answer 1

well, what's 19% of 378000?

`\begin{array}ll \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{19\% of 378000}}{\left( \cfrac{19}{100} \right)378000}\implies 71820~\hfill \underset{current~value}{\stackrel{378000-71820}{\text{\LARGE 306,180}}}`
