      (Show Source): 
You can put this solution on YOUR website! let the number of tapes = x Cost is 8100 + (0.30) x, units in dollars.
 Revenue is 3x
 8100 +0.30 x > 3x  (profit is what is requested, not break even)
 8100 >2.70 x, subtracting 0.30 x from both sides
 divide by 2.70
 x > 3000
 At 3000 tapes, the cost is 8100 (0.3)*3000=$9000
 3000 tapes at $3/tape =$9000
 The answer is 3001. or >3000
 Both work
 It is C.
