Because he’s taxed by his home planet, Mork pays a tax rate of 30% on his income, while Mindy pays a rate of only 20% on hers. If Mindy earned 3 times as much as Mork did, what was their combined tax rate? Pick one:
A) 32.5 %
B) 34 %
C) 35 %
D) 36 %
E) 22.5 %

Rationale: say morks income is - 100 so tax paid will be 30 say mindys income is 3 * 100 = 300 so tax paid is 20 % * 300 = 60 total tax paid = 30 + 60 = 90 . combined tax % will be 90 / 100 + 300 = 22.5 %
