A distillation column processes two types of crude oil streams: North Texas and Venezuelan. Because of consumer demand, the production of diesel fuel, and home heating oil must be limited. Based on the information in Table 1, estimate the optimum daily usage rate of each crude oil to maximize profit, P. The profit generated on processing North Texas (A) and Venezuelan crude (B) is $2.00/ gal and $1.60/gal, respectively. Table.1 Crude oil usage and production information. Venezuelan (%) Maximum Production rate (gal/day) North Texas (%) Diesel Fuel Home heating oil 8 10 30 50 2000 6000
