I've forgotten most of what I've learned about quadratics, and I need someone to help me with the following problem and its graph.
The graph below shows the number of people who will buy a product at a given price (sorry about the dollar signs):
A. How many people will buy the product when the price is $10?
B. If you want 60 people to buy the product, how much should you charge for it?
C. How much money will this generate for the company selling the product?
D. From the information provided in the graph, create a new graph of the amount of money the sales of the product will generate for each selling price from 0 to 23 dollars.
