other sales strategies.

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.
