The correct option is A 6
A proportional relationship between x and y can be represented by the equation: y = mx
Where, m is the rate of change=yx
Here, x = Time taken to make pens
y = Number of pens
So, m=424=16
∴ Equation for the proportional relationship is:
y=16x
Comparing it with the value given, we get:
Value of A = 6
