According to him, the product's design can be modified if the company will use a modern equipment that is now available in the local market. Naturally, acquisition of this modern equipment will mean additional costs for the company, but Mr. dela Cruz is optimistic that the increase in sales due to the increase in selling price will more than cover the incremental cost. When Miss Santiago made an analysis of Mr. dela Cruz' plan, her study revealed the following: * The increase in selling price will increase the contribution margin ratio to 50%. .

Required: Determine the following, assuming that RPI Enterprises will implement Mr. dela Cruz' proposal: Increase in total sales b. Increase in fixed cost C. Expected increase in profit
