Natural Science Using the same assumptions about octane ratings as in Example, solve the following problems.

A service station has 92-octane and 98-octane gasoline. How many liters of each gasoline should be mixed to provide 12 liters of 96-octane gasoline for a chemistry experiment?

Example

Business An oil company needs to fi ll orders for 89-octane gas, but has only 87- and 93-octane gas on hand. The octane rating is the percentage of isooctane in the standard fuel. How much of each type should be mixed together to produce 100,000 gallons of 89-octane gas?
