The city of Hafr-Al Batin is in process of approving a construction site for a new 220,000ft stadium. Two sites have been proposed. The table provides data about proposed (contiguous) properties in both sites together with the acquisition cost. UNUNL Site 1 Site 2 Property Area (1000ft?) Cost ($1000) Area (1000ft?) Cost ($1000) 1 20 1000 80 2800 2 50 21000 60 1900 3 50 2350 50 2800 4 30 1850 70 2500 5 60 2950 Partial acquisition is possible. At least 80% of property 4 must be acquired if sitel is selected, and at least 60% of property 3 is acquired if site 2 is selected. Although site 1 property is more expensive, the construction cost is less than site 2 because of better existing infrastructure at site 1. Construction cost at site 1 is $30 million and at site 2 is $32 million. Determine LP model(s) to decide which site is cheaper for constructing the new stadium. (HINT: Only after you spend one week and cannot figure, consult me). 6. A refinery manufactures two grades of jet fuel, Jl and J2, by blending four types of gasoline, A, B, C, and D. Fuel Jl uses gasolines A, B, C and D in ratio of 1:1:2:4 and Fuel J2 uses gasolines A, B, C and D in ratio of 2:2:1:3. The supply limits for A, B, C, and D are 1000, 1200, 900 and 1500 bbl/day, respectively. The cost per bbl for gasolines for A, B, C, and D are $120, $90, 100 and $150. oll for $200 and $250 per bbl, respectively and minimum demand for
