The high temperature (in degrees Fahrenheit), $x$, and the ice cream sales for a local store, $y$, are related by the regression line equation $\mathrm{y}=8.791\mathrm{x}-392.966$.

Find the amount of sales predicted by the model if the high temperature is $\mathrm{x}={94}^{\circ }\mathrm{F}$. Give your answer as a monetary amount rounded to the nearest cent.
$\mathrm{\$}238.39$
$\mathrm{\$}832.39$
$\mathrm{\$}233.39$
$\mathrm{\$}433.39$

Step 1 ：Given the regression line equation $y=8.791x-392.966$, where $x$ is the high temperature in degrees Fahrenheit and $y$ is the ice cream sales for a local store.

Step 2 ：We are asked to find the predicted sales when the high temperature is 94 degrees Fahrenheit. This can be found by substituting $x=94$ into the regression line equation.

Step 3 ：Substituting $x=94$ into the equation gives $y=8.791(94)-392.966$.

Step 4 ：Solving the equation gives $y=433.38800000000003$.

Step 5 ：Rounding to the nearest cent gives $y=433.39$.

Step 6 ：Final Answer: The predicted sales when the temperature is 94 degrees Fahrenheit is approximately $\boxed{{\displaystyle 433.39}}$ dollars.
