Question: PROJECTED U.S. GASOLINE USAGE The White House wants to cut the gasoline usage from 140 billion gallons per year in 2007 to 128 billion gallons per year in 2017. But estimates by the Department of Energy's Energy Information Agency suggest that won't happen. In fact, the agency's projection of gasoline usage from the beginning of 2007 until the beginning of 2017 is given by

A(t) = 0.014t² + 1.93t + 140    (0 ≤ t ≤ 10)

Where A(t) is measured in billions of gallons/year and t is in years, with t = 0 corresponding to 2007.

a. According to the agency's projection, what will be gasoline consumption at the beginning of 2017?

b. What will be the average consumption/year over the period from the beginning of 2007 until the beginning of 2017?
