Question
Your company asked you to analyze the investment of their advertising campaign. You create a scatterplot graph of the advertising dollars spent on advertising, x , and compare it to the revenue generated, y , for January to December of the campaign. You find the equation of the trend line to be y=2.53x+43 . Predict the revenue generated if your company invests $200.00 in advertising. Write the revenue in dollars and cents.(1 point)
The revenue generated for a $200.00 investment in advertising is $
.
I apologize for the mistake. The correct calculation is as follows:
Given the equation of the trend line: y = 2.53x + 43
Substitute x = 200 into the equation to find y:
y = 2.53(200) + 43
y = 506 + 43
y = 549
Therefore, the revenue generated for a $200.00 investment in advertising is $549.00.
The revenue generated for a $200.00 investment in advertising is $506.

You work for a manufacturing company on a production line that manufactures cell phones. You are paid $30 a day plus $0.75 for each phone that you assemble. Predict your wages if you assemble 100 phone in one day, using the equation of the trend line y=0.75x+30 , where x is the number of phones assembled in one day and y is the total wages. Write your wages in dollars and cents.(1 point)
Your wages are $
.
To predict your wages if you assemble 100 phones in one day using the equation y = 0.75x + 30:
Substitute x = 100 into the equation:
y = 0.75(100) + 30
y = 75 + 30
y = 105
Therefore, your wages for assembling 100 phones in one day would be $105.00.
