To find out how many degrees represent rent on a circle graph, we can use the following relationship:

  1. A full circle is 360 degrees.
  2. The percentage of the circle that corresponds to rent can be calculated as follows:

\[ \text{Degrees for rent} = \left(\frac{\text{Amount spent on rent}}{\text{Total expenses}}\right) \times 360 \]

Given that Sara spent \( $1240 \) on rent out of a total of \( $6200 \):

\[ \text{Degrees for rent} = \left(\frac{1240}{6200}\right) \times 360 \]

First, calculate the fraction:

\[ \frac{1240}{6200} = 0.2 \]

Now, multiply this fraction by 360 degrees:

\[ \text{Degrees for rent} = 0.2 \times 360 = 72 \]

So, the degree measurement that represents rent on the circle graph is:

72 degrees.
