Question 172453: 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)).

Question 172529: I would appreciate any help on the below questions. I have tried to answer, but am not sure if this is correct.
The costs of doing business for a company can be found by adding fixed costs, such as rent, insurance, and wages, and variable costs, which are the costs to purchase the product you are selling. The portion of the company’s fixed costs allotted to this product is $300, and the supplier’s cost for a set of tile is $6 each. Let x represent the number of tile sets.
c. If b represents a fixed cost, what value would represent b?
d. Find the cost equation for the tile. Write your answer in the form C = mx + b.
For question C above I used b = 300. Is this correct?
for question D above I used C = -50x + 300 is this correct?

Question 172627: Solve the problem that involves computing expected values in a game of chance.
A game is played using one die. If the die is rolled and shows a 2, the player wins $8. If the die shows any number other than 2, the player wins nothing. If there is a charge of $1 to play the game, what is the game's expected value?
Here are some thoughts on how to solve... not sure if I am thinking in the right direction:
Get a 2 the prob. is 1/6 and win $8.00 but pay $1 to play
not a 2 is 5/6 and owe a dollar
1/6*8/1= 8/6...4/3=1.33 - $1.00= $.33
