Final answer:
Pierre earns 25% of what he sells and made $6000. To find the total sales value, solve the equation 0.25 * x = $6000, resulting in a total sales value of $24000.
Step-by-step explanation:
If Pierre, a businessman, earns 25% of the dollar value of what he sells and made $6000 this month, we can use this information to calculate the total dollar value of what he sold.
To find out the total sales, we set up the equation where 25% (or 0.25) multiplied by the total sales amount (which we will call 'x') equals Pierre's earnings ($6000).
0.25 * x = $6000
To solve for 'x', we divide both sides of the equation by 0.25:
x = $6000 / 0.25
x = $24000
Therefore, the total dollar value of what Pierre sold this month is $24000.
