Work Step by Step
Typical percentage problem:
What percent ($n$, as a decimal number) of (the base amount $y$) is $x?$
Translated:$\quad n\cdot y=x$
---
Here, What percent ($n$, as a decimal number) of ($y=1,500,000$) is ($x=300,000$)$?$
Translated:$\quad n\cdot 1,500,000=300,000$
... divide with $1,500,000$
$ y=0.2\qquad$ .... convert to percent notation,
(move the decimal point two places to the right and write a percent symbol.)
$=20\%$ were sport utility vehicles
$100\%-20\%=80\% $ were other types of vehicles.
