217. A long long time ago when petrol was only 46 cents a gallon, I pulled in to fill up my car. I gave the gas attendant a $20.00 bill and waited for my change. Unfortunately, he charged me for the number of gallons of gas that the car needed instead of the dollar amount. (for example if the car took 9.4 gallons he would have charged me $9.40. Because of this, I got back less in change than I should have. The weird thing is that I had got back in change the exact amount that I should have been charged for the petrol in the first place. Knowing that the cash indicator on the petrol pump will only charge to the nearest half-cent, how many gallons of petrol did I buy that day?
