The Herschel Candy Company produces a single product: a chocolate almond bar that sells for \(\$ 0.40\) per bar. The variable costs for each bar (sugar, chocolate, almonds, wrapper, and labor) total \(\$ 0.25\). The total monthly fixed costs are \(\$ 60,000\). Last month, bar sales reached 1 million. However, the president of Herschel Candy Company was not satisfied with its performance and is considering the following options to increase the company's profitability:

1. Increase advertising 2. Increase the quality of the bar's ingredients and simultaneously increase the selling price 3. Increase the selling price with no change in ingredients Required

a. The sales manager is confident that an intensive advertising campaign will double sales volume. If the company president's goal is to increase this month's profits by \(50 \%\) over last month's, what is the maximum amount that can be spent on advertising that doubles sales volume?

b. Assume that the company increases the quality of its ingredients, thus increasing variable costs to \(\$ 0.30\) per bar. By how much must the selling price per unit be increased to maintain the same breakeven point in units?

c. Assume next that the company has decided to increase its selling price to \(\$ 0.50\) per bar with no change in advertising or ingredients. Compute the sales volume in units that would be needed at the new price for the company to earn the same profit as it earned last month.
