A refinery can purchase two types of crude oil, Brent or West Texas Intermediate (WTI). It processes these crude oils into two products, gasoline and heating oil. A barrel(bbl) of Brent yields 0.7 bbls of gasoline and 0.3 bbls of heating oil. A barrel of WTI yields 0.4 bbls of gasoline and 0.6 bbls of heating oil. Brent costs $68/bbl and WTI costs $60/bbl. The refinery needs to produce at least 12, 000 bbls/day of gasoline and 4, 800 bbls/day of heating oil. How many barrels of Brent and WTI to purchase and process daily to meet the daily demand for gasoline and heating oil at minimum cost. (DO NOT SOLVE.)
