Question

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).

Answer 1

just a sec.

Answer 2

ok

Answer 3

which appendix is that?

Answer 4

appendix c

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

thank you so much!!!!

Answer 9

No problem! ^_^

Answer 10

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

Answer 11

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

Answer 12

Oh Yes.

Answer 13

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