Final answer:
To calculate the gain or loss on the sale of the vacant lot, subtract the total expenses from the selling price. Sam gained $10,640 on the sale.
Step-by-step explanation:
To calculate the gain or loss on the sale of the vacant lot, we need to subtract the total expenses from the selling price. Sam paid $350 per year in taxes, $150 per year on maintenance, and $90 per year on miscellaneous expenses. So the total expenses over the four years would be:
$350/year * 4 years = $1400
$150/year * 4 years = $600
$90/year * 4 years = $360
The total expenses would be: $1400 + $600 + $360 = $2360
Now we can calculate gain or loss:
Selling Price - Total Expenses = Gain/Loss
$13,000 - $2360 = $10,640
So Sam gained $10,640 on the sale of the vacant lot.
