hmm the reduction is 8%, how much is 8% of 15400 anyway?
if we take 15400 to be the 100%, what is 8%?
[tex]\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
15400&100\\
x&8
\end{array}\implies \cfrac{15400}{x}=\cfrac{100}{8}\implies \cfrac{15400\cdot 8}{100}=x[/tex]
so, the reduced price of the car is 15400 - x.
