Answer:
($2,400,000)
Step-by-step explanation:
The computation of change in operating income is shown below:-
Operating income before = $380 - $320
= $60 per television
Total operating income = Operating income before per television × Television per year
= $60 × 150,000
= $9,000,000
New operating income = $360 - $320) × 165,000
= $40 × 165,000
= $6,600,000
Change in operating income = New operating income - Total operating income
= $6,600,000 - $9,000,000
= ($2,400,000)
