Mathematics
To determine how much Zargon Ziff must sell in order to earn $500, we need to find the total sales amount that corresponds to his commission. We know that he keeps one eighth of his sales as a commission. So, to find the total sales amount, we can set up the equation:
Total Sales Amount = Commission / Commission Rate Since Zargon wants to earn $500 and his commission rate is one eighth (or 1/8), we have:
Total Sales Amount = $500 / (1/8) = $500 * (8/1)
= $4,000 Therefore, Zargon Ziff must sell $4,000 worth of vacuum cleaners to earn $500.
