Show Worked Solution

$\text{Pay hours}$	$= 14.5+3\times 2.5$
	$=22$

$\text{Earnings for 1 hour}$	$=\dfrac{319}{22}$
	$=$14.50$

$\therefore \text{Aurora earns}\ $14.50\ \text{in 1 hour.}$

\(\text{Pay hours}\)	\(= 14.5+3\times 2.5\)
	\(=22\)

\(\text{Earnings for 1 hour}\)	\(=\dfrac{319}{22}\)
	\(=$14.50\)
