Maxine works at an amusement park.She recorded the number of ice cream cones sold each day,along with the high temperature in Fahrenheit degrees.Using her data,she wrote a linear regression equation of y = 9x - 487.If the temperature,or x,is 85°F,how many ice cream cones could Maxine expect to sell?
A) 245
B) 278
C) 753
D) 765
Linear Regression Equation

Final Answer :
B
Explanation :
To find the expected number of ice cream cones sold at 85°F, substitute x = 85 into the linear regression equation y = 9x - 487. This gives y = 9(85) - 487 = 765 - 487 = 278.
