Thrust T of Propeller

Under certain conditions, the thrust T of a propeller varies jointly as the fourth power of its diameter d and the square of the number n of revolutions per second. Show that, if n is doubled and d is halved, the thrust T is decreased by 75%.

T = thrust of propeller

d = diameter

n = number

k = constant of proportionality

Is my equation set up correct? If so, I can then take it from here.

T = (d^4)(n^2)k
