(6 marks) B. Zircon Ltd is a company selling customised t-shirts and reported a meagre profit each year. The business profit calculation for last year, 2020, is as follows: Sales revenue (4,000 units x $25) Less: Variable costs Contribution margin Less: Fixed costs Profit $100,000 (40,000) 60,000 (44,000) 16,000 Concurrent with the national initiative to promote family-friendly tourism in 2021, the company decided to have a more visible presence in the market. The management believes this objective can be achieved through aggressive marketing of the t-shirts. This effort will require spending of an additional $20,000 in a fixed advertising cost. The marketing cost is expected to increase the price of the t-shirts to $30 per t-shirt, while sales volume will likely experience a significant jump by 50% to 6,000 units. Variable cost per unit will remain the same as last year. (TASK] i. ii. Show the calculation of the expected profit for Zircon Ltd's operation in 2021.
