Colonial Tap Company (CTC) is a manufacturer of taps and fittings for the plumping trade, located in Brisbane. CTC manufactures an extensive range of high quality brass and chrome taps. The business is small and has never been able to employ an accountant. Instead, a bookkeeper calculates monthly profit as sales revenue minus expenses. Prices are based on rough estimates of cost of direct materials and direct labour plus a 50% markup. With the decline in profit and constant pressure on prices, Michael Hall, CTCs manager, began to feel uneasy about the way costs and profits are calculated. The results for the month just ended were:
