Answer: the salesperson earns $54 as commission.
Step-by-step explanation:
A furniture salesperson earns 4.5% commission on every piece of furniture sold. The salesperson sells a sofa for $1000. This means that the commission that he earned from the sale of the sofa is
4.5/100 × 1000 = 0.045 × 1000 = $45
The salesperson also sold a chair for $200. This means that the commission that he earned from the sale of the chair is
4.5/100 × 200 = 0.045 × 200 = $9
The total commission that the salesperson earns is
45 + 9 = $54
