The price of crude oil during the period 2000-2010 can be approximated by P(t) = 6t + 18 dollars per barrel (0 st s 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 sts 10).t Use these models to estimate Saudi Arabia's daily oil revenue and also its rate of change in 2002. (Round your answers to the nearest $1 million.) daily oil revenue million rate of change in 2002 $ million/yr
