Answer:
Step-by-step explanation: This is a question under linear regression analysis.
The question is trying to relate sales (in $1000) and and advertising.
Both sales and advertising are variables and are connected by the equation
Y = 32x + 8
Which is a linear regression equation of 2 variables.
Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.
At $1 of adverts, we have $40 of sales.
We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)
Y = 32(1) + 8
Y = 32 + 8
Y = $40.
You can make an equation with these numbers.
182 ÷ 2 = 91 ÷ 2 = 45.5
