whoever answered my last question didnt even try. please answer CORRECTLY for an upvote.

(a) Formulate a linear programming model for maximizing total profit contribution. (Let P1= units of product i produced, for i=1,2,3.) Max s.t. Departiment A Department B Department C p1,P2,p3=0 (b) Solve the linear program formulated in part (a). How much of each product should be produced, and what is the projected total profit contribution (in dollars)? (P1,P2,P3)=() with profit \$\$ y, be the 0-1 variable that is one if any quantity of product i is produced and zero othenwise, for j=1,2,3.) What is the objective function of the mixed-integer linear program? Max In addition to the constraints from part (a), what other constraints should be added to the mixed-integer linear program? s.t. Units of Product 1 produced units of Product 2 produced units of Product 3 produced P1,P2,P30;y1,y2,y3=0,1 (e) Solve the mixed-integer linear program formulated in part (d).
