John and Ingrid pay 30% and 40% tax annually, respectively. If John makes $56000 and Ingrid makes $74000, what is their combined tax rate?	Choose one.
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 74000/128000 = 74/128 = 37/65 is a little above 1/2. Thus, our answer is just a little above 35.   Answer: 35.6%
