Using the equation of the trend line, y=6.52x+30 , predict the sales in dollars and cents if the temperature is 70° Fahrenheit.(1 point) Responses If the temperature is 70° Fahrenheit, the sales of ice cream is $75.64. If the temperature is 70 degrees Fahrenheit, the sales of ice cream is $75.64. If the temperature is 70° Fahrenheit, the sales of ice cream is $106.52. If the temperature is 70 degrees Fahrenheit, the sales of ice cream is $106.52. If the temperature is 70° Fahrenheit, the sales of ice cream is $30.09. If the temperature is 70 degrees Fahrenheit, the sales of ice cream is $30.09. If the temperature is 70° Fahrenheit, the sales of ice cream is $486.40.

Answer 1

To predict the sales of ice cream based on the temperature using the equation of the trend line \( y = 6.52x + 30 \), we need to substitute \( x \) with the temperature, which is 70 degrees Fahrenheit.

Now, let's perform the calculation:

1. Substitute \( x = 70 \) into the equation:
\[
y = 6.52(70) + 30
\]

2. Calculate \( 6.52 \times 70 \):
\[
6.52 \times 70 = 456.4
\]

3. Add 30 to the result:
\[
y = 456.4 + 30 = 486.4
\]

So, when the temperature is 70 degrees Fahrenheit, the predicted sales of ice cream is **$486.40**.

Therefore, the correct response is: **If the temperature is 70° Fahrenheit, the sales of ice cream is $486.40.**
