Final answer:
Jen at Best Buy earns a total of $739 weekly, which includes $400 from her hourly wage and $339 from her 6% commission on sales.
Step-by-step explanation:
Jen at Best Buy earns $10 an hour plus a 6% commission on her sales. To calculate her total weekly earnings, we need to determine her hourly earnings and commission earnings and then add them together.
First, she worked a 40-hour work week, so her earnings from her hourly rate are:
40 hours * $10/hour = $400
Next, her commission is 6% of her total sales of $5,650 which is calculated as:
6% * $5,650 = 0.06 * $5,650 = $339
Finally, to find her total weekly earnings, we add her hourly earnings to her commission earnings:
$400 + $339 = $739
Therefore, Jen's total weekly earnings are $739.
