Need AMPL solution along with formulation typed there are already other solution available only need AMPL code with formulation

2-70. A refinery manufactures two grades of jet fuel, Fl and F2, by blending four types of gasoline, A B, C and D. Fuel Fl uses gasolines A, B, C, and D in the ratio 1:1:2:4, and fuel F2 uses the ratio 2:2:1:3. The supply limits for AB, C and Dare 1000, 1200, 900, and 1500 bbl/day, respectively. The costs per bbl for gasolines A, B, C, and D are $120, S90, $100, and $150, respectively. Fuels Fl and F2 sell for $200 and $250 per bbl, respectively. The minimum demand for F1 and F2 is 200 and 400 bbl/day, respectively. Develop an LP model to determine the optimal production mix for Fl and F2, and find the solution using AMPL, Solver, or TORA
