Answer
$\text{Rating }\approx
91.0
$
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 $A=
658
,$ $C=
448
,$ $T=
33
,$ $Y=
4620
,$ and $I=
22
,$ then
\begin{array}{l}\require{cancel}
\text{Rating = }
\dfrac{\left(250\cdot\dfrac{
448
}{
658
} \right)+\left(1000\cdot\dfrac{
33
}{
658
} \right)+\left(12.5\cdot\dfrac{
4620
}{
658
} \right)+6.25-\left(1250\cdot\dfrac{
22
}{
658
} \right)}{3}
\\\\
\text{Rating = }
90.86246
\\\\
\text{Rating }\approx
91.0
.\end{array}
