Acompany makes greeting cards and their research shows that that price and demand are related linearly: p = mx + b. they know that for every additional card they wish to sell they need to drop the price by $0.05. they also know that in order to sell 360 cards they need to set the price at $4. find the linear equation relating price to demand. p= 0 preview

The linear equation relating price to demand is

Step-by-step explanation:

A Linear Demand Function expresses demand p (the number of items demanded) as a function of the unit price x (the price per item).

From the information given we know two facts:

Let x be the price and p the number of cards sold.

The fact 1. is the slope of the function because is the change in demand per unit change in price.

We can use fact 2. to find the value of b in the equation

The linear equation relating price to demand is

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

x = 23.78
