An underground gasoline tank at 46F can hold 1500 gallons of gasoline. If the driver of a tanker truck fills the under-ground tank on a day when the temperature is 88F, how much (according to his gauge on the truck) can he pour in? Assume that the temperature of the gasoline cools to 46F upon entering the tank and its thermal coefficient of expansion is 0.00096 (C)-1. Answer in units of gal
