a. Suppose 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).

just a sec.

ok

which appendix is that?

appendix c

The two points are: (42,20) and (52,10) Slope: (10-20)/(52-42) Slope= -10/10 Slope= -1 Substituting the values: y = mx+b 20 = -1(42) + b b = 62 so: p(x) = -x + 62

is that the answer i put or do it have to be in (x,p) form?

It says: a. Write your answer in the form p = mx + b

thank you so much!!!!

No problem! ^_^

so i'm saying p(x)=-x+62 is my final answer after all of that?

are u like those people who dont get algebra at all?

Oh Yes.

i am....most of it I dont get for real...but i'm trying though

lol, alright.. best of luck with your coming weeks.

I have a feeling you'll be hearing from me again...LOL

Thanks again

Haha, Sure. the best part, i got the same feeling as well. LOL.
