To predict the revenue generated from a $200.00 investment in advertising using the equation of the trend line \( y = 2.53x + 43 \), you can substitute \( x = 200 \) into the equation.
\[ y = 2.53(200) + 43 \] \[ y = 506 + 43 \] \[ y = 549 \]
Therefore, the revenue generated for a $200.00 investment in advertising is $549.00.
