I was charged $ 1.20 for sales tax when I spent $20. How much sales tax would I pay on a purchase of $50
NARA [144]

well, keeping in mind that taxes are a percent of the price value, so we know that 1.20 is really some percent of 20, whilst 20 is the 100%, so what is 1.20 off of it in percentage?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 20&100\\ 1.20&x \end{array}\implies \cfrac{20}{1.20}=\cfrac{100}{x}\implies 20x=120 \\\\\\ x=\cfrac{120}{20}\implies x=6\qquad \impliedby \textit{so then the tax applied is 6\%} \\\\[-0.35em] ~\dotfill\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{6\% of 50}}{\left( \cfrac{6}{100} \right)50}\implies 3

Plisss help write the linear equation that vives the rule for this table ​
sineoko [7]

well, we know is a line,  and to get the equation of any straight line all we need is two points, hmmm let's use from the table hmm say (2 , -50) and hmmm (4 , -88)

(\stackrel{x_1}{2}~,~\stackrel{y_1}{-50})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-88}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-88}-\stackrel{y1}{(-50)}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-88+50}{2}\implies \cfrac{-38}{2}\implies -19

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-50)}=\stackrel{m}{-19}(x-\stackrel{x_1}{2}) \\\\\\ y+50=-19x+38\implies y=-19x-12
