T would be 72 because 2x2=4 and 4x18=72
For equations that model direct variation, they are of the form y = kx, where k is the constant of proportionality.
So, for there to be a constant of proportionality of 1/2, the equation should be y = 1/2 x.
This is the same as y = 3/6 x (since 1/2 = 3/6), so the answer is C.
7.48 pounds are equal to approximately 3.39 kilograms.
