pat, kate, and mark charged a total of 126 hours to a certain project. if pat charged twice as much time to the project as kate and 1 / 3 as much time as mark, how many more hours did mark charge to the project than kate?	Options:
A) 18 B) 36 C) 72 D) 70 E) 108

<output>1/3 = around 0.333333</output>

<gadget id="calculator">1 + (1/3)</gadget>
<output>4/3 = around 1.333333</output>

<output>1/6 = around 0.166667</output>

<gadget id="calculator">(4/3) + (1/6)</gadget>
<output>3/2 = around 1.5</output>

<gadget id="calculator">126 / (3/2)</gadget>
<output>84</output>

<gadget id="calculator">84 / 6</gadget>
<output>14</output>

<gadget id="calculator">84 - 14</gadget>

subtract(divide(126, add(add(1, divide(1, 3)), divide(1, multiply(3, const_2)))), divide(divide(126, add(add(1, divide(1, 3)), divide(1, multiply(3, const_2)))), multiply(3, const_2)))
"70 all u do is do 2 : 1 : 6 = > 2 x + x + 6 x = 126 = > x = 14 28 : 14 : 84 84 - 14 = 70 answer d"
