The high temperature (in degrees Fahrenheit), \( x \), and the ice cream sales for a local store, \( y \), are related by the regression line equation \( y=8.571 x-325.212 \). Find the amount of sales predicted by the model if the high temperature is \( x=81^{\circ} \mathrm{F} \). Give your answer as a monetary amount rounded to the nearest cent.
