Explanation Given: Total units of aluminium and steel available with the company are 91,800 and 42,000, respectively. The racing bikes require 17, touring bikes require 27 and mountain bikes require 34 units of steel whereas the racing bikes require 12, touring bikes require 21 and mountain bikes require 15 units of aluminium. Profits are made of $8 per racing bikes, $12 per touring bikes and $22 per mountain bikes. Calculation: Assume the number of bikes manufactured under each of the three categories be represented by x 1 , x 2 and x 3 , respectively. Construct a table in order to fetch from the given information as follows. Racing Touring Mountain Amount available Steel 17 27 34 91,800 Aluminium 12 21 15 42,000 Profit $8 $12 $22 Obtain the first constraint as 17 x 1 + 27 x 2 + 34 x 3 ≤ 91 , 800 since the racing bikes require 17, touring bikes require 27 and mountain bikes require 34 units of steel as well as total units of aluminium available with the company is 91,800. Obtain the second constraint as 12 x 1 + 21 x 2 + 15 x 3 ≤ 42 , 000 since the racing bikes require 12, touring bikes require 21 and mountain bikes require 15 units of aluminium as well as total units of steel available with the company is 42,000. Obtain the objective function which represents the maximized profits which the manufacturer enjoys as follows. z = 8 x 1 + 12 x 2 + 22 x 3 The linear programming problem can be stated as follows. Maximize z = 8 x 1 + 12 x 2 + 22 x 3 subject to 17 x 1 + 27 x 2 + 34 x 3 ≤ 91 , 800 12 x 1 + 21 x 2 + 15 x 3 ≤ 42 , 000 with x 1 ≥ 0 , x 2 ≥ 0 , x 3 ≥ 0 Add slack variables to the above constraints and obtain the linear programming problem as follows
