Answer:
The number of packages of chocolate chip cookies sold was 44 and the number of packages of sugar cookies sold 161
Step-by-step explanation:
Let
x ----> the number of packages of chocolate chip cookies sold
y ----> the number of packages of sugar cookies sold
we know that
 -----> equation A
 -----> equation A
 -----> equation B
 -----> equation B
Solve the system of equations by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (44,161)
see the attached figure
therefore
The number of packages of chocolate chip cookies sold was 44 and the number of packages of sugar cookies sold 161
 
        
             
        
        
        
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

substitute the coordinates of the points (8, 0) and (20, 12) to the formula:

y = 1x + b = x + b
Put the coordinates of the point (8, 0) to the equation of a line:
0 = 8 + b      <em>subtract 8 from both sides</em>
-8 = b
<h3>Answer: y = x - 8</h3>
