Oxford Engineering manufactures small engines. The engines aresold to manufacturers who install them in such products as lawnmowers. The company currently manufactures all the parts used inthese engines but is considering a proposal from an externalsupplier to supply the starter assembly used in these engines.Thestarter assembly is currently manufactured in Division 3 of OxfordEngineering. Last year, Division 3 manufactured 160,000 starterassemblies, but over the next several years, it is expected that200,000 assemblies will be needed each year. Total costs related tothe starter assembly for last year were as follows:
Direct material $329,600
Direct labor $179,200
Totaloverhead $800,000
Total $1,308,800
Further analysis of overhead revealed the followinginformation:
55% of total overhead was fixed.
$100,000 of the fixed overhead were allocated costs that willcontinue even if the production of the starter assembly isdiscontinued.
Tidnish Electronics, a reliable supplier, has offered to supplystarter assembly units at $5.50 per unit. If the company buys theassembly from Tidnish, sales of another product can be increased,resulting in additional contribution margin of $44,000.
1. By how much will Oxford Engineering's total profits change ifthey decide to buy the starter assembly from Tidnish Electronicsinstead of making itthemselves? (Note: if the buycosts are less than the make costs, enter the difference as apositive number; if the make costs are less than the buy costs,enter the difference as a negative number.)
