Since we are given the values for both rows only in the second column, we can use this to solve for the rest of the missing values. Simply divide 3 by 2.49 and multiply that resultant by and multiply that by any missing value for cookies to find the missing cost. In order to solve for the cookies when cost is given, divide 2.49 by 3 and multiply that resultant. I will solve for the first, third, and fourth columns.
3/29=1.2
For column 1, 1.2*1=1.20
For column 3, 1.2*20=24.10
For column 4, 1.2*100=12.00

Step-by-step explanation:
<u>The Equation of a Line</u>
The equation of the line in slope-intercept form is:

Where m is the slope and b the y-intercept.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

We are given the points (5,2) and (0,-1), thus:

Operating:


To find the slope-intercept form, we continue to simplify the expression:
Removing the parentheses:


Adding 2:


The answer to the problem is 40in
