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)).

A company’s revenue is the amount of money that comes in from sales, before business costs are subtracted. For a single product, you can find the revenue by multiplying the quantity of the product sold, x, by the demand equation, p.

b. Substitute the result you found from part a into the equation R = xp to find the revenue equation. Provide your answer in simplified form.

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.

The profit made from the sale of tiles is found by subtracting the costs from the revenue.

e. Find the Profit Equation by substituting your equations for R and C in the equation . Simplify the equation.

f. What is the profit made from selling 20 tile sets per month?

g. What is the profit made from selling 25 tile sets each month?

h. What is the profit made from selling no tile sets each month? Interpret your answer.

i. Use trial and error to find the quantity of tile sets per month that yields the highest profit.

j. How much profit would you earn from the number you found in part i?

k. What price would you sell the tile sets at to realize this profit (...

My son is having great difficulty undestanding how to write linear equations for word problems. I can`t help him without getting help myself:).

I think it will help me understand equations and problems my teacher doesn`t explain enough to me.

I am hoping I will learn how to do word problems related to Solving Systems of Linear Equations in Two Variables. It is an area I am having the most trouble.. especially related to distance (2 autos traveling at different speeds, etc.) problems where speed is unknown.

It will help my son understand how to do the problems and understand equations and so on.

To better understand the concept of math equations, and how to do the formulas for add math problems.

Need to have tips on formulating equations for word problems.

I have trouble with systems of equations, and the videos show me step by step how to work out the problem.

My weakest area in Math is in expressing the equation/equations based on the given data in the statements of the mathematical problem. With your site it is hoped I can remedy my weakness by practicing to solve the worded problems and together with the other students I can check my progress the right way. Thank you for putting up this site.

I think that you`d help broaden my understandings with math and i think that you`d make it enjoyable for me to work on problems and equations provided by your site.

I hope it helps me with word problems and linear equations.

It will help me help my children with their problems solving math equations.

This site will help me understand math equations, solutions, and problems more than I can from school.
