We can start by setting up a proportion:
$100/8 = x/9$
We can solve for $x$:
$8x = 900$
$x = 112.50$
Therefore, the constant of proportionality is $112.50/9 = 12.50$.
The answer is C.
$100/8 = x/9$
We can solve for $x$:
$8x = 900$
$x = 112.50$
Therefore, the constant of proportionality is $112.50/9 = 12.50$.
The answer is C.
