(b) The Sales Manager makes the following proposal: He forecasts that annual sales would increase by 10% if Y2L Ltd incurs an additional annual advertising expenditure of $45,490. With the increase in marketing effort, he forecasts that the selling price could be increased to $329 per tent. Y2L Ltd is planning to source for cheaper raw materials from another supplier and expects material cost will reduce to $1.50 per square metre. To meet the increase in production from the additional sales and to further improve the profitability, Y2L Ltd plans to increase the direct wage rate from $8 to $12 per hour as part of a productive deal that could cut the labour hours needed from 5 hours to 3 hours per tent for all units to be produced and sold. The Sales Manager is confident that the company is able to achieve the 10% increase in sales forecast for 2022 if his proposal is implemented. Assume all other costs remain unchanged.
