Answer:
945 minutes
Explanation:
The first step is to find 10% of 450:
10 times 450 is 4500 and 100 times 1 is 100
Then 4500 divided by 100 and the answer is 45 minutes.
After that add that 10% of 450 ( 45 ) to 450 to find the minutes he reads in the next month and the answer is 495 minutes.
So because you want the time he read in the two months add 450 and 495 tp get:
450 + 495 = 945
So Oliver read for 945 in the 2 MONTHS.
