Question 104291: The octane rating of a gasoline is a measure of the amount of iso-octane in the gas. How much 87-octane gas should be blended in order to end up with 12gal of 91-octane gas?
87x + 93y = 12 x 91
87x + 93y = 1092
87x = -93y + 1092
x = -93y/-87 + 1092/-87
x = 31/29 + 364/29 Answer by scott8148(6628) (Show Source):
