Because he’s taxed by his home planet, Mork pays a tax rate of 40% on his income, while Mindy pays a rate of only 30% on hers. If Mindy earned 2 times as much as Mork did, what was their combined tax rate?
Choose the correct choice from the following answers:
A) 32.5%  B) 34%  C) 22.5%  D) 33.3%  E) 37.5%

<gadget id="calculator">2*100</gadget>
<output>200</output>
200   So tax paid is 30% * 200= 60   Total tax paid = 40+60= 
<gadget id="calculator">40+60</gadget>
<output>100</output>
100.   Combined tax % will be 100/100+200= 33.3%
<result>D</result>
