1.
In this problem, we will analyze the profit found for sales of decorative tiles. A
demand
equation
(sometimes called a demand curve) shows how much money people would pay
for a product depending on how much of that product is available on the open market.
Often, the demand equation is found empirically (through experiment, or market
research).
a.
Suppose that a market research company finds that at a price of p = $20, they
would sell x = 42 tiles each month. If they lower the price to p = $10, then more
people would purchase the tile, and they can expect to sell x = 52 tiles in a
month’s time. Find the equation of the line for the demand equation. Write your
answer in the form p = mx + b. (Hint: Write an equation using two points in the
form (x,p).
