The answer is b. 200

<span>If y varies inversely as x, then: y = c/x

We know:
y = 40
x = 5

y = c/x
c = y * x
c = 40 * 5
c = 200</span>

Answer:

b. 200

Step-by-step explanation:

We have been given that y varies inversely as x.

Since we know that equation that represents the inversely proportional relation between y and x is:y=\frac{k}{x}, where,

k= Constant of proportionality.

Upon substituting our given values in above equation we will get,

40=\frac{k}{5}

Let us multiply both sides of our equation by 5.

40\times 5=\frac{k}{5}\times 5

200=k

Therefore, constant of proportionality for our given quantities is 200 and option b is the correct choice.
