450 minutes this month. 10% more next one. Total for 2 months. 1) Let's find 10% of 450 and add it to 450 to find out how much he reads next month. 450×0.1=45 450+45=495 minutes 2) Now that we know Oliver reads 495 minutes next month, to find the total, we should add the two. 495+450=First month plus second month=945 •°•Oliver, in total, read 945 minutes during the two months.
