Answer:</h2>
The value of the constant in the equation below is:
B. 60
<h2>
Step-by-step explanation:</h2>
It is given in the graph that:

i.e. we may also say that:

We observe that the graph passes through (2,30) , (5,12) , (10,6) , (30,2)
So, by using any one point we may get the value of constant( since it is a fixed quantity)
Hence, using the point (2,30)
i.e. Width=2 and Height=30 we get:

Hence, the value of constant is:
60
