Question

Solve and analyze the following problems. Make sure all steps are properly justified. Correctly uses mathematical notation or terminology. Interpret the solution in the context of the problem.

Suppose the supply and demand equations for posters for a graduating class are given by
p = 1.6q + 5.2 (supply)
p = -2.4q + 18 (demand)
where p is the price in dollars and q is the quantity in hundreds.
Determine the supply and demand if the posters cost $6.00. Prepare the graph of the two equations in the same coordinate system and identify the break-even point and quantity. Prepare a graph of both equations and determine what each region means.

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
