Answer
$\text{Rating }\approx
100.2
$
Work Step by Step
Using the given formula, $
\text{Rating = }\dfrac{\left(250\cdot\dfrac{C}{A} \right)+\left(1000\cdot\dfrac{T}{A} \right)+\left(12.5\cdot\dfrac{Y}{A} \right)+6.25-\left(1250\cdot\dfrac{I}{A} \right)}{3}
,$ where $A=
372
,$ $C=
233
,$ $T=
21
,$ $Y=
3018
,$ and $I=
6
,$ then
\begin{array}{l}\require{cancel}
\text{Rating = }
\dfrac{\left(250\cdot\dfrac{
233
}{
372
} \right)+\left(1000\cdot\dfrac{
21
}{
372
} \right)+\left(12.5\cdot\dfrac{
3018
}{
372
} \right)+6.25-\left(1250\cdot\dfrac{
6
}{
372
} \right)}{3}
\\\\
\text{Rating = }
100.1792
\\\\
\text{Rating }\approx
100.2
.\end{array}
