To determine the value of X for the equation \( Y = 42.9 + 143.3X \), we first need to convert the advertising expenditure of $36,231.00 into the appropriate units.
Since advertising (X) is in units of $1,000, we convert $36,231.00 into thousands:
\[
X = \frac{36,231.00}{1,000} = 36.231
\]
Now, you can substitute this value of X into the equation:
\[
Y = 42.9 + 143.3 \times 36.231
\]
So, to summarize, you would use \( X = 36.231 \) in the equation \( Y = 42.9 + 143.3X \) to calculate the value of sales.
Since advertising (X) is in units of $1,000, we convert $36,231.00 into thousands:
\[
X = \frac{36,231.00}{1,000} = 36.231
\]
Now, you can substitute this value of X into the equation:
\[
Y = 42.9 + 143.3 \times 36.231
\]
So, to summarize, you would use \( X = 36.231 \) in the equation \( Y = 42.9 + 143.3X \) to calculate the value of sales.
