The following problems are worth ten (10) points each.

1. Bazooka Company is thinking about introducing a new type of color printer. If they introduce it, their factory will incur additional fixed costs of $37,000,000 per year. The variable costs will be $261 per printer. a) If Bazooka sells the new printer for $819, how many must they sell to break even? QBE = FC/SP-VC = $37,000,000/$819-$261 = $37,000,000/$558 = 66,308 Printers b) If Bazooka sells 70,000 of the new printer at the $819 price, what will the contribution to profit be? Profit = Revenue – Cost = 70,000*$819-[$37,000,000+(70,000*$261)] = $57,330,000-[$37,000,000+$18,270,000] = $57,330,000-$55,270,000 = $2.060,000

Which service line has the highest hourly productivity? Pizza: P = O/I = 90/1 = 90 pizzas/hour Salad: P = O/I = 140/(70/60)*2 = 140/2.33 = 60 salads/hour Sandwich: P = O/I = 360/(90/60)*3 = 360/4.5 = 80 sandwiches/hour Pizza line has the highest hourly productivity
