A refinery has two crude gils with the xields given in the following table. Because of equipment

and storage limitations$.$ production of gasoline kerosene and fuel oil must be limited as shown in

the same table. The profit on processing crude no $1$ is $$\frac{0\mathrm{.}95}{h}$arrel and on processing srude no $2$

is $$\frac{0\mathrm{.}75}{?}$ harrel. Let the xolume of crude no $1$ used $($barrel$/$day$)$ is $x_1,$ and of crude ne $2$ used

$($barrel$//$day$)$ is $x_2.$

a$)$ In order to determine the optimum daily feed rates $(x_1$ and $x_2)$ of the two crudes that

maximizes the daily profit prepare a mathematical statement $($objective function,

constraints etc.$)$ of this problem. Discuss if this is a linear or nonlinear programming

problem.

b$)$ Solve the optimization problem using Excel Solver. What are the optimum yalues of $xl$ and

$x_2?$ What is the maximum daily profit?

PLS ALL OF THE DETAILS.
