Show Worked Solution

$\text{Percentage spent on the treadmill}$	$=\dfrac{2460}{6000} \times 100$
	$=41\text{%}$

$\text{Percentage on spin bike}=100-(41+28)=31\text{%}$

$\therefore\ \text{Amount spent on spin bike}$	$=31\text{%}\times 6000$
	$=31\times 60$
	$=$1860$

\(\therefore\ \text{Amount spent on spin bike}\)	\(=31\text{%}\times 6000\)
	\(=31\times 60\)
	\(=$1860\)

\(\text{Percentage spent on the treadmill}\)	\(=\dfrac{2460}{6000} \times 100\)
	\(=41\text{%}\)
