Linear programming python code using pyomo, numpy and pandas for following problem:

Several types of petrol are produced during a petroleum refining process, and a last step combines them to obtain market products with specified quality measures.

Suppose $4$ different types of petrol are available, with values for the $2$ indexes of quality being $74$ and $148,95$ and $185,100$ and $182,$ and $102$ and $195,$ respectively.

Costs per litre of petroleum are $0\mathrm{.}22,0\mathrm{.}83,0\mathrm{.}94,$ and $0\mathrm{.}43$ respectively.

What is the minimal cost $($in pounds$)$ of a blend of petrols with a first quality index between $95$ and $100$ and a second index between $182$ and $185?$
