Question

The weight (V) of an object on Venus varies directly as its weight (E) on Earth. A person weighing 120 lb on Earth would weigh 106 lb on Venus. How much would a person weighing 180 lb on Earth weigh on Venus?

Answer 1

Direct variation means y=kx so (inverse variation means y=k/x)

106=120k so k=53/60

V(E)=53E/60

V(180)=159lb
