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

How many liters of 94-octane gasoline should be mixed with 200 liters of 99-octane gasoline to get a mixture that is 97-octane gasoline?

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?
