Suppose that during 1992-1998, a country consumed gasoline at a rate of about
q(t) = 3.6t + 240 billion gallons per year. (0 ≤ t ≤ 6)

(t is the number of years since 1992.) During the same period, the price of gasoline was approximately
p(t) = 1.0e0.02t dollars per gallon.

Use an integral to estimate, to the nearest billion dollars, the total spent on gasoline during the given period. HINT
[Rate of spending = p(t)q(t).]

______billion dollars
