Final answer:
Rebecca's $34,500 earnings represented a 5% commission on her total sales. To find the total sales, divide the commission earned by the commission rate. The total sales value for the quarter was $690,000.
Correct option is a) $690,000
Step-by-step explanation:
To calculate the total value of Rebecca's sales last quarter, we will use the given commission rate of 5%. The $34,500 that Rebecca earned is the commission from the total sales, so we assume that this amount represents the 5% commission. We can set up a simple equation to find the total sales (let's call it T).
The equation based on the given commission will be:
0.05 * T = $34,500
To find T, we divide both sides of the equation by 0.05:
T = $34,500 / 0.05
T = $690,000
Therefore, the total value of her sales last quarter was $690,000.
