Hi! Since Oliver read 450 minutes during the first month, there'd be a 10% increase of minutes during the next month. To find the 10% increase, we need to divide 450 by ten, and add this quotient to 450.

Our result is 495. Oliver will read 495 minutes during the second month. Next we'll add 495 and 450 to get our final answer: 945 total minutes of reading during the two months.
