Answer:
The combined expenses in Years 3 and 4 were $300,000 more than the combined income of Years 3 and 4.
Step-by-step explanation:
The combined income in years 1, 2, and 3 is $1,400,000 and the combined expenses in the same years is $1,500,000; so number 1 is incorrect.
Expenses have increased $100,000 each year over the last 5 years. Year 1 = $400,000 , Year 2 = $500,000 , Year 3 = $600,000 , Year 4 = $700,000 , Year 5 = $800,000. So number 3 is incorrect.
Year 1's income was $600,000 and Year 5's income was $900,000. Twice Year 1's income would have been $1,200,000. So number 4 is incorrect.
