To predict the revenue generated for a $200.00 investment in advertising using the trend line equation \( y = 2.53x + 43 \), we will substitute \( x \) with 200 in the equation.
\[ y = 2.53(200) + 43 \]
Calculating \( 2.53 \times 200 \):
\[ 2.53 \times 200 = 506 \]
Now, we add 43 to this result:
\[ y = 506 + 43 = 549 \]
Therefore, the predicted revenue generated for a $200.00 investment in advertising is $549.00.
