Answer:

1) 500     2) $ 1000 debt    3) $350    4) $2500 debt

Step-by-step explanation:

profit = .5x -250  

1)  O      = .5x -250

250 = .5x

500 = x      number to break even

2)   f(900) =  .5 (900) -250 =  $200

       from the graph  g(200) = total debt = $1000

3)   f(x) = -75  = .5x-250    results in    x = $ 350

4)    f(500) = .5(500) - 250 = 0  

      from the graph, this corresponds to total debt g (f(500) = $2500 debt
