Question 1128014: A magazine company had a profit of $98,000 per year when it had 32,000 subscribers. When it obtained 38,000 subscribers, it had a profit of $117,500. Assume that the profit P is a linear function of the number of subscribers s.
(a) Find the function P.
P(s) =
(b) What will the profit be if the company obtains 50,000 subscribers?
$
(c) What is the number of subscribers needed to break even? (Round to the next highest subscriber.)

You can put this solution on YOUR website! The problem gives us two ordered pairs, (32,000 , $98,000) and (38,000 , $121,500
With this information we can establish the folowing equations:
m = (y2 - y1)/(x2 - x1)
y = mx + b
Slope m = (P2 - P1)/(S2 - S1) = ($117,500 - $98,000)/(38,000 - 32,000) = $19,500 / 6,000 = $47 / 12

For the function, P(s), the slope is NOT  .
Just thought I'd let you know. Everything will be wrong if you go along with that WRONG slope.
