Hi
n = kt
20 = k*5/2
8 = k
n = 8t
135 = 8t
t = 16.875 hrs
the profit margin of producing x number of plasma tv's can be model by the
function Q(x)=5000%2F%28270-.4x%29
Q(100)=5000%2F%28270-.4%2A100%29 = 5000/230= $21.74
Q(500)=5000%2F%28270-.4%2A500%29 = 5000/70 = $71.43
Q(750)=5000%2F%28270-.4%2A750%29 = 5000/-30 = -$166.67
function undefined when: 270-.4x = 0 OR when x = 675
