Airplane fuel worth $126 per pound and $135 per pound is mixed with a third variety of high grade fuel in the ratio 1:1:2. If the resultant mixture is worth $153 per pound, the price of the third variety of fuel per pound will be:
A. $169.50
B. $170
C. $175.50
D. $180
E. $205


Letting n = the price per pound of the third variety of fuel, we can create the following equation:

(126x + 135x + n(2x)) / (4x) = 153

261x + 2nx = 612x

261 + 2n = 612

2n = 351

n = 175.5
