Answer:
($15,000)
Explanation:
The computation of net income will increase (decrease) is given below:-
First we need to find out the relevant cost per unit which is shown below:-
Total relevant cost = Direct material + Direct labor + Variable overhead + Fixed overhead
= $60,000 + $165,000 + $80,000 + $45,000
= $350,000
Relevant cost per unit = Total relevant cost ÷ Number of units to be produced
= $350,000 ÷ 5,000
= $70
Price of supplier per unit = $73
Net increase in cost per unit = ($73 - $70) $2
Number of units to be produced = 5,000
Decrease in net income = Number of units to be produced × Net increase in cost per unit
= 5,000 × $2
= $15,000
