<PRE><B>Question 390844</B>
the linear profit model means that the income per steer (slope) is constant , but there is also overhead or fixed costs (intercept)


20 more cattle (50 - 30) bring in 8000 more dollars (12500 - 4500)
so the income per steer is ___ 8000/20 or 400


30 cattle means income of 12000 , but only 4500 profit
this indicates a fixed cost (overhead) of 7500 ___ this checks out for 50 cattle


the equation is ___ p = 400c - 7500


plug in 75 for c to find your answer</PRE>
