Step-by-step explanation:
Given that z varies directly with y and x then the equation relating them is
z = kxy ← k is the constant of variation
To find k use the condition x = 6, y = 12 and z = 10
k = = = = , hence
z = xy ← equation of variation

Step-by-step explanation:
Answer:
total amount of students in the class = 24
