Sales(Y) is in Units of $10,000.00 and Advertising(X) is in Units of $1000. If we want to calculate the value of sales when $36,231.00 is spent on advertising. What do we use for X in the following equation? Y=42.9+143.3X.

Answer 1

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.
