 When price P is fixed by the government at $.75, then what is the corresponding Q supply and demand?  Looking at the table, the corresponding Q in the supply column is 20 gallons, and the corresponding Q in the demand column is 40 gallons.  The lower number is what matters, because nothing can be bought unless it is both supplied and demanded.  So the supply is 20 gallons and that is what is sold at $.75 per gallon.  That is 20 times 0.75 = $15 per person, or $15,000 for the whole town.  Some may try to buy and sell gas illegally at a higher price, as illegal markets often develop when there are price controls.
