Sean is practicing for his role in a theater production. He has to memorize his lines for two scenes and the lyrics to one solo song. His solo song has 54 lines in the lyrics. The first scene has twice the number of lines, but only a third of them are his lines. The second scene has six more lines than the song, and four-fifths of them are his. How many lines does Sean have to memorize?
The first scene has twice the number of lines as his solo song, so it has 2 * 54 = 
<gadget id="calculator">2*54</gadget>
<output>108</output>
108 lines.
A third of them are Sean's lines, so he has to memorize 108 / 3 = 
<gadget id="calculator">108/3</gadget>
<output>36</output>
36 lines.
The second scene has 54 + 6 = 
<gadget id="calculator">54+6</gadget>
<output>60</output>
60 lines.
Four fifths of the second scene's lines are Sean's, so he has to memorize 4 * 60 / 5 = 4 * 12 = 
<gadget id="calculator">4*60/5</gadget>
<output>48</output>
48 lines.
Sean has to memorize his entire solo song, so he has to memorize 54 + 36 + 48 = 
<gadget id="calculator">54+36+48</gadget>
<output>138</output>
138 lines in all.
