To predict the revenue generated for a $200 investment in advertising, you can use the equation of the trend line:
\[ y = 2.53x + 43 \]
where \( x \) is the amount spent on advertising.
Substituting \( x = 200 \):
\[ y = 2.53(200) + 43 \] \[ y = 506 + 43 \] \[ y = 549 \]
Thus, the predicted revenue generated for a $200 investment in advertising is:
$549.00
