$\text{Plane ticket has had 10% added to the price.}$

$\therefore\ $1716\ \text{represents}\ 110\text{%}\ \text{of the original price}$

$\therefore\ \dfrac{110}{100}\ \times\ \text{Original price}$	$=$1716$
$\therefore\ \text{Original price}$	$=\dfrac{$1716\times 10}{11}$
	$=$1560$

\(\therefore\ \dfrac{110}{100}\ \times\ \text{Original price}\)	\(=$1716\)
\(\therefore\ \text{Original price}\)	\(=\dfrac{$1716\times 10}{11}\)
	\(=$1560\)
