4. Hulk Industries produces and sells a single product. The selling price of the product is $198 per unit and its variable cost is $142 per unit. The fixed expense is $64,688 per month. (12 pts) a. Compute the breakeven point in units. b. How many units must Hulk Industries sell to reach a target profit of $386,200 ? c. Assume the Hulk is currently selling 5,000 units. The production and marketing managers would like to make the following changes-decrease the selling price by $5, and decrease the per unit cost by $2 and increase the advertising budget by $30,000 per month. They predict that introducing these changes would increase monthly sales by 800 units. Is this a good idea or not? Show your work
