Prudence was starting a cupcake business.  She figured that each cupcake cost $0.75 to make.  The first 2 dozen that she made burnt and she had to throw them out.  The next 2 came out perfectly and she ended up eating 5 cupcakes right away.  Later that day she made 2 more dozen cupcakes and decided to eat 4 more. If she sells the remaining cupcakes at $2.00 each, how much is her net profit?
She burnt 2 dozen, cooked 2 dozen and then another 2 dozen that evening. So she made 2+2+2 =

<output>6</output>
6 dozen cupcakes.
Each dozen makes 12 cupcakes, so she made 6*12= 
<gadget id="calculator">6*12</gadget>
<output>72</output>
72 cupcakes.
She threw away 2 dozen cupcakes, so 2*12 = 
<gadget id="calculator">2*12</gadget>
<output>24</output>
24 cupcakes.
She made 72, threw away 24, ate 5 and then ate another 4 so she had 72-24-5-4 = 
<gadget id="calculator">72-24-5-4</gadget>
<output>39</output>
39 cupcakes left.
She sells the 39 cupcakes at $2.00 each so she earned 39*2 = $
<gadget id="calculator">39*2</gadget>
<output>78</output>
78.00.
She made 72 cupcakes at a cost of $0.75 each for a total cost of 72*$0.75 = $
<gadget id="calculator">72*0.75</gadget>
<output>54</output>
54.00.
If she made $78 on the remaining cupcakes and it cost her $54.00 to make all of the cupcakes then her profit is $78-$54 = $
<gadget id="calculator">78-54</gadget>
<output>24</output>
24.00.
