Please help me figure out part c. The answer must be a percentage.

A product at the Jennings Company enjoyed reasonable sales volumes, but its contributions to profits were disappointing. Last year, 15,000 units were produced and sold. The selling price is $23 per unit, the variable cost is $19 per unit, and the fixed cost is $68,000. a. What is the break-even quantity for this product? Use both graphic and algebraic approaches to get your answer. O O O Revenue The break-even quantity according to the algebraic approach is Q = 17000 units. (Enter your response as an integer.) line A Cost livre To obtain the result with the graphic approach, plot the following: 1.) Using the line drawing tool, draw the total cost line. Properly label the line. $1,000,0007 $900,000 $800,000 $700,000 $600,000 $500,000 $400,000+ $300,000 2.) Using the line drawing tool, draw the total revenue line. Properly label the line. 3.) Using the point drawing tool, plot the point that corresponds to the break-even quantity. Label this point 'Q'. Carefully follow the instructions above, and only draw the required objects. $200,000 $100,000 b. If sales were not expected to increase, by how much would Jennings have to reduce their variable cost to break even? $06 10,000 30,000 40,000 20,000 Quantity (Q) The variable cost would have to reduce from $19 to $ 18.47 per unit. (Enter your response rounded to two decimal places.) c. Jennings believes that a $1 reduction in price will increase sales by 50 percent. Is this enough for Jennings to break even? If not, by how much would sales have to increase? The sales have to be increased by at least Enter your response rounded to the nearest whole number.)
