Please only answer questions 4-B and 6, the rest was complete and added for context, thanks!

Stratford Company distributes a lightweight lawn chair that sells for $30 per unit. Variable expenses are 20% of sales, and fixed expenses total $595,200 annually. Required: Answer the following independent questions: 1. What is the product's CM per unit? 2. Use the CM per unit to determine the break-even point in units. 3. The company estimates that sales will increase by $60,000 during the coming year due to increased demand. By how much should net operating income increase? 4. Assume that the operating results for last year were as follows: a. Compute the degree of operating leverage at the current level of sales. (Round your answer to 1 decimal place.) b. The president expects sales to increase by 30% next year. By how much should net operating income increase? 5-a. Refer to the original data. Assume that the company sold 32,000 units last year. The sales manager is convinced that a 8% reduction in the selling price, combined with a $144,000 increase in advertising expenditures, would increase annual unit sales by 40%. Prepare two contribution format income statements: one showing the results of last year's operations, and one showing what the results of operations would be if these changes were made. (Do not round intermediate calculations. Round "Per Unit" answers to 2 decimal places.) 5-b. Would you recommend that the company do as the sales manager suggests? Yes No 6. Refer to the original data. Assume again that the company sold 32,000 units last year. The president feels that it would be unwise to change the selling price. Instead, she wants to increase the sales commission by $3 per unit. She thinks that this move, combined with some increase in advertising, would double annual unit sales. By how much could advertising be increased with profits remaining unchanged? Do not prepare an income statement; use the incremental analysis approach. Answer is complete but not entirely correct
