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.

(A) The a scatter plot is attached below.

(B) The line of best fit is y = 1149.8 + 53.8 x.

(C) The coupon is responsible for the restaurant's increase in pizza sales on Tuesdays.

(D) The restaurant's sales for the Tuesday of the 15th week is $1,956.80.

Step-by-step explanation:

(A)

The a scatter plot and the line of best fit to represent the data in the table is attached below.

(B)

The total sales for week 4 is, $1,365.

The total sales for week 9 is, $1,634.

Compute the equation for the line of best fit as follows:

Thus, the line of best fit is y = 1149.8 + 53.8 x.

(C)

The slope of the line represents the average rate of change in y with respect to x.

The slope of the line of best for the sales of pizza is 53.8.

The slope is positive.

This implies that the coupon is responsible for the restaurant's increase in pizza sales on Tuesdays.

(D)

Compute the value of y for x = 15 as follows:

Thus, the restaurant's sales for the Tuesday of the 15th week is $1,956.80.

5x+10 is the correct one

hope this

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
