Step-by-step explanation:
The net income of Errera Corporation can be calculated by subtracting the total costs and depreciation from the total sales. The formula to calculate net income is:
Total Sales - Total Costs - Depreciation = Net Income
In this case, the total sales are $3,110,400, the total costs are $2,776,000, and the depreciation is $258,000.
Subtracting the total costs and depreciation from the total sales, we get:
$3,110,400 - $2,776,000 - $258,000 = $76,400
Therefore, the net income of Errera Corporation is $76,400.
