A magazine company had a profit of $98,000 per year when it had 32,000 subscribers. When it obtained 35,000 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
b.) What will the profit be if the company has a total of 50,000 subscribers?
c.) What is the number of subscribers needed to break even?

you have two points (32000,98000) and (35000,117500)
Find the slope (11750098000)/(3500032000)
put into point slope form
yy0=m(xx0)
using one of the two points for x0 and y0.
b) Plug in x as 50,000 and solve for y.
c) plug in y as 0 and solve for x
