A company blends two gasolines from Xena Fuels and Yuri Petrol (inputs) into two commercial products, Super and Regular gasoline (outputs). For the inputs, the octane ratings, the vapour pressures in kilopascals, and the amounts available in cubic metres (ms) and their prices are known. These are: Input Octane Vapour Amount Buying Price Gasoline Rating Pressure (kPa) Available (m) ($ per m) Xena 106 13,500 80 63 21,000 230 36 280 Yuri For the Super and Regular gasolines the requirements are: Output Minimum Gasoline Octane Rating Super Regular 87 Maximum Minimum Selling Vapour Amount Price Pressure (kPa) Required (m) ($ per m) 42 6,000 310 55 15,000 270 94 We define the variables as follows: X and Y are respectively the amount of gasoline in m purchased from Xena Fuels/Yuri Petrol. S and R are respectively the amount of Su- per/Regular gasoline in my blended and sold. XS, XR, YS, and Y R are respectively the amounts in m3 of Xena/Yuri gasoline used to make Super/Regular gasoline. (a) Formulate an algebraic model for the problem. Submit this in Word or pdf.
