Answer:
the relevant cost to make is $44.35
Step-by-step explanation:
given data
Direct material = $ 8.10
Direct labor = 24.10
Overhead = 40.50
Total product cost per unit = $ 72.70
Cost of purchase = $42.35
solution
we know here that 70% of overhead cost is unavoidable
so we can say that it will not be considered for decision making
so here Cost of manufacturing will be
Cost of manufacturing = $8.10 + $24.10 + ( 30% of $40.50 )
Cost of manufacturing = $44.35
and
Cost of purchase is = $42.35
so here we can say the relevant cost to make is $44.35
