To predict the revenue generated with an investment of $200.00 in advertising, we can use the trend line equation:
\[ y = 2.53x + 43 \]
where \( x \) is the amount spent on advertising.
Substituting \( x = 200 \) into the equation:
\[ y = 2.53(200) + 43 \]
Calculating it step-by-step:
-
Calculate \( 2.53 \times 200 \): \[ 2.53 \times 200 = 506 \]
-
Now add 43: \[ 506 + 43 = 549 \]
So, the predicted revenue generated for a $200.00 investment in advertising is:
\[ y = 549 \]
Therefore, the revenue generated is $549.00.
