The price of crude oil during the period 2000-2010 can be approximated by P(t) = 6t + 18 dollars per barrel (0 ≤ t ≤ 10) in year t, where t = 0 represents 2000. Saudi Arabia's crude oil production over the same period can be approximated by Q(t) = −0.036t2 + 0.62t + 8 million barrels per day (0 ≤ t ≤ 10). † Use these models to estimate Saudi Arabia's daily oil revenue and also its rate of change in 2006.
