For a school play, one adult ticket cost $5 and one student ticket cost $3. Twice as many student tickets as adult tickets were sold. Suppose a fuel mixture is 5% ethanol and 95% gasoline. How much ethanol (in gallons) must you add to one gallon of the fuel so that the new fuel mixture is 10% ethanol? It took him 49.17 s to swim the 50
