To determine how many degrees should represent rent on a circle graph, we need to understand that a full circle represents 100% of the expenses, which is 360 degrees. Since Sara spent 25% of her expenses on rent, we can calculate the degree representation for rent as follows:

  1. Calculate the degree representation: \[ \text{Degrees for Rent} = \text{Percentage for Rent} \times \text{Total Degrees} \] \[ \text{Degrees for Rent} = 0.25 \times 360 \] \[ \text{Degrees for Rent} = 90 \]

So, rent covers 90 degrees of the circle graph.
