Learning Objective: to see how linear and quadratic functions are useful in the business world.
Write what you know about these terms – cost, demand, revenue, and profit.
make a profit
loss of money
2 types of costs
rent, insurance, etc.
Materials, wages, etc.
Dependent on # of items made or hours worked
Cost Function -
Price-Demand Function -
m and n are constants (depending on the problem)
x is the # of items that can be sold at $p per item
Revenue Function -
# of items sold*price per item
Profit Function -
P - Wholesale price per camera
x - millions of cameras sold
* note as price goes down, # sold goes up
a) Plot the data in the table and find the price-demand function. What is the domain?
b) What is the company's Revenue function for this camera? What is the domain of the function?
c) Complete the table, computing revenues to the nearest million dollars
in millions of $s
d) Graph the revenue function and change the window appropriately. Sketch the function below.
What kind of graph is it?
e) What is the max revenue to the nearest $1,000? For what output of cameras (nearest thousand)?
f) What is the wholesale price per camera to nearest dollar to produce the max revenue?
Use the # of cameras that maximizes revenue for x!
g) Given the cost data below, find the cost function for manufacturing the cameras.
h) Find the company's profit function. Graph and find the max profit and output.
7.5 million cameras
Use the # of cameras that maximizes profit for x!
j) Find where the company would break even, run at loss, or have a profit.
Don’t forget about POW!!
