<PRE><B>Question 964136</B>
C(x) = 30x + 1200  R(x) = 38x
a)Total cost=30(50)+1200=1500+1200=2700
b)Profit function  P(x) = R(x) - C(x)=38x-(30x + 1200)=8x-1200
c)Profit for 50 units=8(50)-1200=400-1200=-800
  There is a loss of 800 for 50 units.
d)For break even P(x)=0
8x-1200=0
8x=1200
x=1200/8=150 units
Breakeven occurs at 150 units.
