Question

UpStudy AI · Accepted Answer

To determine the cost of 13 markers when you know that 3 markers cost \$5.79, you can set up a proportion that relates the number of markers to their cost.

The proportion should compare the cost per marker in each scenario:

$$
\frac{3 \text{ markers}}{\$5.79} = \frac{13 \text{ markers}}{x}
$$

This equation allows you to solve for $$ x $$, which represents the cost of 13 markers.

**Correct Answer:**  
**(C) $$ \frac{3}{\$5.79} = \frac{13}{x} $$**
The correct equation to find the cost of 13 markers is $$ \frac{3}{\$5.79} = \frac{13}{x} $$.
