For a certain commodity, the demand equation is given by D= -5p + 5=. At a price of $1, twelve units of the commodity are supplied. If the supply equation is linear and the market price is $4, find the supply equation.

Answer:

For this one I have come up with a formula of:

s= ap+b where p if the varialbe, price, and a,b are constants

s is supply.

I think I have to find a and b but amd not sure.

First you'll need to find out the amount supplied at the market price. Market price is when supply equals demand.

Do you have the equation correct? If D = -5p + 5 and the market price is $4, then you're working in negatives.... Did you mean -5p + 50?

He's already posted half his homework here (http://www.vbforums.com/forumdisplay.php?s=&forumid=20)

So don't bother answering.
