Answer 1

To calculate the percent of increase in rent, you can use the formula:

\[
\text{Percent Increase} = \left( \frac{\text{New Rent} - \text{Old Rent}}{\text{Old Rent}} \right) \times 100
\]

In this case:

- Old Rent = $425
- New Rent = $467.50

Substituting these values into the formula:

\[
\text{Percent Increase} = \left( \frac{467.50 - 425}{425} \right) \times 100
\]

\[
= \left( \frac{42.50}{425} \right) \times 100
\]

\[
= 0.1 \times 100
\]

\[
= 10\%
\]

So, the percent increase in rent is **10%**.

The correct answer is **D) 10%**.
