The rent in an apartment building was increased from $425 to $467.50. What was the percent of increase?
10%
9%
91%
111%
The percent of increase can be found by calculating the difference between the new rent and the original rent, then dividing that difference by the original rent and multiplying by 100.
Difference between the new rent and the original rent = $467.50 - $425 = $42.50
($42.50 / $425) * 100 = 10%
Therefore, the correct answer is 10%.
