Answer 1

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.
