To find the total commission paid on the sale property for $45,000, we can break down the selling price into different ranges and calculate the commission for each range separately.
First, let's calculate the commission for the first range, which is 5% on the first $12,000:
Commission for the first range = 5% of $12,000 = 0.05 * $12,000 = $600
Next, let's calculate the commission for the second range, which is 3% on the next $15,000:
Commission for the second range = 3% of $15,000 = 0.03 * $15,000 = $450
Finally, let's calculate the commission for the third range, which is 1% on the remainder of the selling price:
Commission for the third range = 1% of ($45,000 - $12,000 - $15,000) = 0.01 * $18,000 = $180
Now, we can find the total commission by adding up the commissions from each range:
Total commission = Commission for the first range + Commission for the second range + Commission for the third range
Total commission = $600 + $450 + $180 = $1,230
Therefore, the total commission paid on the sale property for $45,000 is $1,230.
