A cross section is the 2D shape that fallouts from cutting a 3D with a plane.To classify the face shape from cuts made parallel and perpendicular to the bases of right dimensional figures, we need to know first what parallel cuts are. These cuts will form the shape of the base while perpendicular cuts will take the form of the lateral face. Cuts at an angle through the right rectangular prism or pyramid will make a parallelogram.
        
             
        
        
        
Answer:

x ---> the numbers of tickets in advanced sold
y ---> the numbers of tickets at the door sold
we know that
325 tickets are sold
so
 ----> equation A
 ----> equation A
$1430 is collected
so
 ----> equation B
 ----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (260,65)
see the attached figure
therefore
The numbers of tickets in advanced sold was 260 and the numbers of tickets at the door sold was 65
