The total costs incurred at various output levels for a process operation in a factory was measured as follows: Output (in units) Total cost () 11,500 102,476 12,000 104,730 12,500 106,263 13,000 108,021 13,500 110,727 14,000 113,201 Required: i. Using the high-low method, analyse the costs of the process operation into fixed and variable components ii. Calculate, and comment upon, the break-even output level of the process operation in (i) above, based upon the fixed and variable costs identified and assuming a selling price of 10.60 per unit. iii. The earlier the BEP of the firm the better in terms of profitability. Identify ways in which a firm can lower its BEP in order to start making profits earlier.
