Fuel Consumption From 1995 to 2002, the total fuel consumption 7 (in billions of gallons) by cars in the United States and the U.S. population P (in millions) can be modeled byT = -0.003x³ -0.02x² + 1.3x + 68 and P = 3x + 267where x is the number of years since 1995. Write a function for the average amount of fuel consumed by each person from 1995 to 2002.
