Does any one know how to solve this problem
Estimated weekly demand of 200 units at a price of $16 per unit and
Estimated weekly demand of 300 units at a price of $14 per unit.

Assume that the relationship between the price P and the demand x is linear. Use the estimates to express d as a funtion of x and find the domain of this function.

I'm stuck I know how to do this with one estimate, but not two. I tried useing the product rule, and I still cant get this if someone could explain what to do that would be wonderful.

Yes, I know how to do it, but it won't help you. You need to go talk to your teacher, or another student who can explain it to you, and talk you thorough it. Alternatively, you can find yourself a tutor. If you were in the area, I'd be happy to fill that role for you, but bets are you're not. Internet help is no help at all with math.

I've got a tutor he is cant help. Cant get my teacher right now. I know the solution I just need to know how to get it. This is an example out of the book. But they dont show the steps. If I could see this I could figure out how to do the work.
