Answer:
(1) $30,000 + $12x
(2) $50x
(3) $38x - $30,000
(4) 790 CD's to break even
Explanation:
Given that,
Variable cost = $12 per CD
Fixed cost = $30,000
Selling price = $50 each
Let x be the number of CD's produced,
(1) Total cost function:
C(x) = Fixed cost + Variable cost
       = $30,000 + $12x
(2) Total revenue:
R(x) = Units produced × selling price of each unit
       = $50x
(3) Total profit:
P(x) = R(x) - C(x)
       = $50x - ($30,000 + $12x)
       = $50x - $30,000 - $12x
       = $38x - $30,000
(4) Number of CD's which must be produced to break even:
Total profit = 0
$38x - $30,000 = 0
x = $30,000 ÷ $38
   = 789.47 or 790 CD's to break even.
