John and Ingrid pay 30% and 40% tax annually, respectively. If John makes $56000 and Ingrid makes $73000, what is their combined tax rate?	Answers: A) 32% B) 34.4% C) 35% D) 35.6% E) 36.4%
(1) When 30 and 40 has equal weight or weight = 1/2, the answer would be 35.   (2) When 40 has larger weight than 30, the answer would be in between 35 and 40. Unfortunately, we have 2 answer choices D and E that fit that condition so we need to narrow down our range.   (3) Get 73000/129000 = 73/129 is a little above 1/2. Thus, our answer is just a little above 35.   Answer: 35.6%
