The expenses were $63,000. How did I get this:
Net income = revenues - expenses
Plug the corresponding numbers into the formula:
$89,000 = $152,000 - E
Subtract $152,000 from both sides.
$89,000 - $152,000 = -E
$-63,000 = -E
Divide both sides by -1
E = $63,000
The expenses were $63,000
Side note, dividends are not a part of the net income and expenses.
