Final answer:
To find the earnings from a 16% commission on $8000 in sales, you multiply the total sales by the commission rate (0.16), resulting in $1280, which is option A.
Step-by-step explanation:
The calculation needed to determine how much a person would earn from sales totaling $8000 with a 16% commission rate is a simple multiplication. To find the commission, multiply the total sales amount by the commission rate.
In this case, the commission rate is 16%, or 0.16 when expressed as a decimal.
Commission = Total Sales × Commission Rate
Commission = $8000 × 0.16
Commission = $1280
Therefore, a person would earn $1280 from sales totaling $8000, which corresponds to option A.
