$\text{Discount}$	$=\text{Cost Price}-\text{Sale Price}$
	$=45-30.15$
	$=$14.85$

$\text{Percentage Discount}$	$= \dfrac{\text{Discount}}{\text{Cost price}}\times 100\text{%}$
	$=\dfrac{14.85}{45}\times 100\text{%}$
	$=33\text{%}$

\(\text{Discount}\)	\(=\text{Cost Price}-\text{Sale Price}\)
	\(=45-30.15\)
	\(=$14.85\)

\(\text{Percentage Discount}\)	\(= \dfrac{\text{Discount}}{\text{Cost price}}\times 100\text{%}\)
	\(=\dfrac{14.85}{45}\times 100\text{%}\)
	\(=33\text{%}\)
