$$526\mathrm{.}02$ is incorrect. Please help find the correct answer. Problem $11\mathrm{.}037E-$ Fuel consumption for a sign $on$ the roof $of$ a car

Bill gets a job delivering pizzas. The pizza company makes him mount a sign $on$ the roof $of$ his car. The frontal area

$of$ the sign $isA=0\mathrm{.}612f{t}^2,$ and $he$ estimates the drag coefficient $tobe{C}_D=0\mathrm{.}94at$ nearly all alr speeds.

Estimate how much additional money $it$ costs Bill per year $in$ fuel $to$ drive with the sign $on$ his roof compared $to$

without the sign. Use the following additional information: $He$ drives about $10,300$ miles per year $atan$ average

speed $of45mph.$ The overall car efficiency $is0\mathrm{.}332,{}_{\text{f}\text{u}\text{e}\text{l}}=50\mathrm{.}2lb\frac{m}{f}{t}^3,$ and the heating value $of$ the fuel $is$

$1\mathrm{.}53{10}^{7}ft*lb\frac{f}{l}bm.$ The fuel costs $$3\mathrm{.}50$ per gallon. Use standard air properties. $Be$ careful with unit

conversions. ${}_{\text{f}\text{u}\text{e}\text{l}},H{V}_{\text{f}\text{u}\text{e}\text{l}},{}_{\text{a}\text{i}\text{r}}=0\mathrm{.}07518lb\frac{m}{f}{t}^3.$

The additional cost that Bill has $to$ pay per year $is$ $
