I need the solutions for these 2 problems to help in my examination preparation.thanksSample problem 4.Lennox Industries manufactures two products: A and B.  A review of the company's accounting records revealed the following per-unit costs and production volumes:ABProduction volume (units)2,5005,000Direct material$ 40$  60Direct labor:2 hours at $12243 hours at $1236Manufacturing overhead:2 hours at $931863 hours at $93279Manufacturing overhead is currently computed by spreading overhead of $1,860,000 over 20,000 direct labor hours.  Management is considering a shift to activity-based costing in an effort to improve the firm's accounting procedures, and the following data are available:Cost Driver VolumeCost PoolCostCost DriverABTotalSetups$   240,000Number of setups10020120General factory1,500,000Direct labor hours5,00015,00020,000Machine processing     120,000Machine hours2,2008003,000$1,860,000Lennox determines selling prices by adding 40% to a product's total cost.Required:A.Compute the per-unit cost and selling price of product B by using Lennox's current costing procedures.B.Compute B's per-unit overhead cost of product B if the company switches to activity-based costing.C.Compute the total per-unit cost and selling price under activity-based costing.D.Lennox has recently encountered significant international competition for product B, with considerable business being lost to very aggressive suppliers.  Will activity-based costing allow the company to be more competitive with product B from a price perspective?  Briefly explain.E.Will the cost and selling price of product A likely increase or decrease if Lennox changes to activity-based costing?  Why?  Hint: No calculations are necessary.
