Final answer:
Samuel earned a total of $453.80 from his furniture sales.
Step-by-step explanation:
To calculate Samuel's earnings, we need to find the commission for the first $2000 of sales and the commission for the remaining sales over $2000.
Commission for the first $2000 = $2000 * 0.04 = $80
Remaining sales = $8230 - $2000 = $6230
Commission for the remaining sales = $6230 * 0.06 = $373.80
Total earnings = Commission for the first $2000 + Commission for the remaining sales = $80 + $373.80 = $453.80
