Hoping to increase pizza
sales on Tuesdays, a new pizza
restaurant prints and disperses the
following coupon through email and

fliers in a neighborhood marketing magazine

After ten weeks of the coupon offer, the

owner of the restaurant needs to

decide if the restaurant should continue

to run the same special or offer a new
one. Use the data collected in the table to determine whether or not the coupon
appears to be generating sales for the restaurant.
Week Total
Sales


1 $859
2 $1,176
3 $1,480
4 $1,365
5 $1,576
6 $1,498

7 $1,180
8 $1,964
9 $1,634

10 $1,580 Part A: Create a scatter plot and the line of best fit to represent the data in the table. Be sure to label each axis, as well as to include the proper titles for the scatter plot.
• Part B: Use the total sales for weeks 4 and 9 to write an equation for the line of best fit. In your final answer, include all of your calculations.
• Part C: in terms of the slope of the equation for the line of best fit, explain whether or not you think the coupon is responsible for the restaurant's increase or decrease in pizza sales on Tuesdays. Use complete sentences in your answer.
• Part D: Assuming that the pizza restaurant wishes to continue the coupon for an additional five weeks, use the equation for the line of best fit to predict the restaurant's sales for the Tuesday of the 15th week.
