Answer and Explanation:
Given:
Cost of extra worker salary = $69873
Units with extra worker =7700 units per year
Selling price = $15.00
Cost per unit = $7.81
(Direct material = $2.77
Direct labour = $0.90
Variable overhead = $0.24
Fixed overhead = $3.90)
Calculate net income:
Sale revenue($15*7700units) =$115500
Deduct expenses:
Direct material ($2.77*7700units) =$21329
Direct labour($0.90*7700 units)= $6930
Variable overhead(0.24*7700 units) =$1848
Fixed overhead allocated(3.90*7700 units) = $30030
Net profit = $55363
Therefore profit increases with additional worker
