Answer
$\$ 51,200$
Work Step by Step
As per the given problem, we have:
$y=kxz$
Here, $k$ is defined as constant of proportionality
Let us consider $y=V; x=A, z=G$
$V=kAG$
Plug the given data in the above expression, we get
$48000=k(60000)(10)$
This gives: $k=0.08$
Then, we have $V=kAG$
This implies that $V=\dfrac{4}{5}(60000)(4) =\$ 51,200$
