Suppose a market research compay finds that at a price of p=$20, they wwould sell x=42 tiles each month if thh plan t lothe price to p=$10, the more peopl would purchase any tile. and they equation and they sell x=52 tiles in a month's time. find the equation line in the drmand euation. Write the answer in the form p=mx+b.

Solution:

We assume p = mx + b

x = 42, p = 20

x=  52, p = 10

So

m = -1

b = 62

So the equation is

p = -x + 62
