Answer:
To calculate the amount of commission received by Amber, the salesperson, we need to multiply the total sale amount by the commission rate.
Commission = Total sale amount × Commission rate
The total sale amount is $13,000, and the commission rate is 10% (or 0.10).
Commission = $13,000 × 0.10
Commission = $1,300
Therefore, Amber received a commission of $1,300 on the sale of the vacation package to Tiffany and her partner.
