Find an equation for the rational function graph.
-In the following formula, $f ( x )$ is the minimum number of hours of studying required to attain a test score of $x : f ( x ) = \frac { 0.44 x } { 100.5 - x }$. How many hours of study are needed to score 94 ?
A) $100.03 \mathrm { hr }$
B) $14.53 \mathrm { hr }$
C) $6.36 \mathrm { hr }$
D) $63.60 \mathrm { hr }$

To find the number of hours needed to score 94, substitute $x = 94$ into the function: $f(94) = \frac{0.44 \times 94}{100.5 - 94} = \frac{41.36}{6.5} \approx 6.36$ hours.
