Show Worked Solution

a.	\(\text{High ropes and abseiling}\)	\(=9+12\)
		\(=21\ \text{students}\)

b.	\(\text{Average students/activity}\)	\(=\dfrac{15+12+24+9+7+19}{6}\)
		\(=\dfrac{86}{6}\)
		\(=14.333\dots\)
		\(=14\ \text{students (nearest whole number)}\)

c.	\(\text{Difference}\)	\(=24-15\)
		\(=9\ \text{students}\)
