ABC Ltd. Produces widgets for which the demand is unlimited and they can sell all of their production. The graph below describes the monthly variable costs incurred by the company as a function of the quantity produced. In addition, operating the plant for one shift results in a fixed monthly cost of Tk. 800. Fixed monthly costs for second shift operation are estimated at Tk. 1200. Each shift operation provides capacity for producing 30 widgets per month.
